03Preparation overview

Practice the difference between a document, its version and a permission to act on it. This guide uses parsing, SQL selection, auditability and concurrency exercises to make correctness visible. Start by identifying whether you are applying to Veeva’s Engineering Development Program or an experienced engineering role; the published entry-level assessment must not be generalized to every opening.

Focus: Versioned documents · Data integrity · Authorization and audit

05Questions & practice

All cards below are original PracHub editorial practice. Difficulty is an estimate; these are not verified questions asked by the employer. Worked solutions belong to their question, not a second question list.

Coding

Validate a nested delimiter sequence

Easy · Stacks · Input validation

Given a string containing only (), [] and {}, determine whether every opening delimiter is closed in the correct nesting order. The empty string is valid. Reject other characters explicitly. This deliberately small grammar is not a JSON parser or a validator for a real Vault document.

Approach

1. Use a stack of opening delimiters. On a closing delimiter, the most recent opening character must be its matching partner.
2. Reject a closing delimiter when the stack is empty, and reject non-delimiter input rather than silently treating arbitrary document content as valid.
3. After the scan, the stack must be empty. Balanced counts alone are insufficient: ([)] has equal counts but invalid nesting.
4. Time is O(n) and worst-case auxiliary space is O(n). Explain how a maximum allowed nesting depth would protect a real parser from excessive input.

Worked solution · 25 minutes

1. The expected opener is determined by the current closer. This catches incorrect nesting even when character counts match.
2. Rejecting unsupported characters keeps the exercise’s grammar honest. A production parser needs explicit tokenization and escaping rules.

def balanced(text):
    expected = {')': '(', ']': '[', '}': '{'}
    stack = []
    for char in text:
        if char in '([{':
            stack.append(char)
        elif char in expected:
            if not stack or stack.pop() != expected[char]:
                return False
        else:
            raise ValueError("unsupported character")
    return not stack

Expected result: ([]{}) and the empty string return True. ([)] and a lone ] return False. An alphabetic character raises an input error.

Checks

• Test an unclosed opener and a leading closer.
• Test mixed valid nesting.
• Reject unsupported text and discuss depth limits.

Follow-up

• How would the contract change if quotes allowed literal bracket characters?
• How would you return the first invalid character position rather than only a boolean?

Keep entity identity stable in a hash collection

Medium · Object-oriented design · Equality · Collections

A document object is placed in a set and later its status changes. Membership checks begin failing because hashCode and equals include status. Explain the bug and choose identity rules for a document versus a specific document version. Use the semantics of your interview language.

Approach

1. Fields used by equality and hashing must remain stable while an object is used as a hash key. A mutable workflow status is usually a poor identity field.
2. Separate an entity key such as tenant plus document ID from a version key that also includes immutable revision identity.
3. Test two objects representing the same identity, two different tenants and a state transition after insertion. Discuss the cost of immutable value objects versus entity references.

Follow-up

• When would two different versions intentionally compare equal, and when would that be a defect?

SQL

Find the latest approved document version

Medium · Window functions · Versioned records

document_versions(tenant_id, document_id, version, status) stores unique integer versions. For tenant a, return the highest approved version of each document that has one, even if a newer draft exists. The fixture assumes rows are already authorized for the reader. It is a training schema, not a Vault API query or an access-control implementation.

Approach

1. Filter to approved versions before ranking. Ranking every version first and then checking status would wrongly hide an older approved version when the latest version is a draft.
2. Partition by the complete document identity, including tenant. Order by the defined numeric version, not a display string such as 1.10 that may sort incorrectly.
3. Select row number one from each partition. Documents with no approved version should be absent rather than having a draft presented as approved.
4. Keep authorization distinct from business selection. In a real system, selecting an approved revision does not automatically imply that the caller may view it.

Worked solution · 30 minutes

1. Business filtering precedes ranking: first choose approved rows, then choose the newest among them.
2. The exercise’s integer version removes major/minor ambiguity so the result can be tested directly.

WITH approved AS (
  SELECT tenant_id, document_id, version,
         ROW_NUMBER() OVER (
           PARTITION BY tenant_id, document_id
           ORDER BY version DESC
         ) AS position
  FROM document_versions
  WHERE tenant_id = 'a' AND status = 'approved'
)
SELECT document_id, version
FROM approved
WHERE position = 1
ORDER BY document_id;

Expected result: A document with approved versions 1 and 2 plus draft version 3 returns version 2. A document containing only drafts is absent.

Checks

• Keep an older approval when a newer draft exists.
• Exclude another tenant’s newer approval.
• Handle documents without an approved revision.

Follow-up

• How would major and minor version numbers change the ordering?
• What if approval can be revoked or a version superseded?

System design

Design versioned documents with auditable approvals

Hard · Versioning · Authorization · Audit trails

Design a document service where users upload immutable versions and authorized reviewers approve a specific revision. A document may have a newer draft and an older approved version. Explain how concurrent edits, permission changes and an interrupted upload affect what readers and reviewers see. This is an original design exercise inspired by document-workflow concepts.

Approach

1. Separate stable document identity, immutable content version and mutable workflow state. An approval must identify the exact version reviewed; approving a name or latest pointer is ambiguous.
2. Stage the binary upload and verify its content hash before making a metadata record visible. An object-store write and a database transaction need an explicit recovery protocol.
3. Validate permission, allowed state transition and expected revision at the mutation boundary. Record an audit event atomically with the business-state change.
4. Keep readers’ selection rules explicit: latest draft, latest approved and latest visible are different queries. Define retention and revocation with the product owner rather than inventing a regulatory rule.

Worked solution · 50 minutes

1. Use separate metadata records for document identity, content versions, workflow transitions and audit events. Record the exact content hash or version in the approval.
2. Stage binary content, commit its metadata reference only after verification, and reconcile abandoned staging objects. A database rollback cannot undo an arbitrary object-store write.
3. Use expected revision plus authorization at the approval boundary. Return a conflict when the reviewer’s view is stale rather than applying approval to a different revision.
4. Define how a retry retrieves the prior accepted result, and how notifications are eventually sent after the durable state change.

Expected result: A reviewer never accidentally approves an unseen revision. Failed audit persistence leaves state unchanged, and an interrupted upload has a documented cleanup or recovery path.

Checks

• Edit a document between review and approval.
• Revoke permission before a command is accepted.
• Crash after binary upload but before metadata commit.

Follow-up

• What happens if approval succeeds but the client loses the response?
• How does the design handle an orphaned uploaded object or a missing binary after restore?

Debugging

Reject a stale or unauthorized approval

Medium · Optimistic concurrency · Transactions · Audit

A reviewer opens revision 7, but the document changes to revision 8 before the approval is submitted. The current handler checks permissions in the browser and then approves whatever is newest. Repair the server-side mutation so it checks current permission, draft state and the expected revision, and writes an audit event only when the transition succeeds.

Approach

1. Treat browser checks as presentation only. The server must enforce the permission and object identity on every mutation.
2. Use a conditional update against the expected revision and allowed state. A zero-row update is a conflict or denial, not success; expose a safe error and reload the current record.
3. Commit the audit record with the state change. If auditing fails, roll back the approval rather than producing an unaudited transition.
4. Define the ordering of concurrent permission revocation and approval. The SQLite exercise models an atomic local transaction; production needs an isolation/locking policy consistent with its authorization contract.

Worked solution · 35 minutes

1. The example uses documents(tenant_id, document_id, revision, status), permissions(tenant_id, document_id, user_id, can_approve), and audit(tenant_id, document_id, user_id, revision).
2. revision is an optimistic concurrency token in this local model. The code is not a Vault endpoint or a claim about Vault’s permission implementation.

def approve(db, tenant, document_id, user_id, expected_revision):
    with db:
        changed = db.execute(
            "UPDATE documents SET status='approved', revision=revision+1 "
            "WHERE tenant_id=? AND document_id=? AND revision=? "
            "AND status='draft' AND EXISTS ("
            "SELECT 1 FROM permissions p WHERE p.tenant_id=? "
            "AND p.document_id=? AND p.user_id=? AND p.can_approve=1)",
            (tenant, document_id, expected_revision,
             tenant, document_id, user_id),
        ).rowcount
        if changed != 1:
            return False
        db.execute(
            "INSERT INTO audit VALUES (?,?,?,?)",
            (tenant, document_id, user_id, expected_revision),
        )
    return True

Expected result: A stale expected revision or absent permission returns False and creates no audit event. A valid transition changes one document and adds one audit entry for the reviewed revision.

Checks

• Reject a stale revision.
• Reject permission from another tenant.
• Force audit insertion to fail and verify that approval rolls back.

Follow-up

• How would you provide enough conflict detail without revealing a document the caller can no longer access?
• Which stable request identifier makes an approval retry distinguishable from a new action?

Investigate a slow audit-history query

Medium · Indexes · Pagination · Measurement

A document’s audit panel becomes slow as history grows. The API filters by tenant and document, sorts newest first and returns 50 records. Explain how you would investigate it and design stable pagination without assuming a specific database engine.

Approach

1. Capture query shape, examined rows, ordering work and response size for representative large histories. Separate database time from serialization and network time.
2. Evaluate an index aligned with tenant, document and the chosen ordering. Include a unique event ID as a tie-breaker when timestamps can repeat.
3. Prefer a cursor contract based on the full order key when appropriate. Test concurrent new events so page boundaries do not unpredictably duplicate or omit older records.

Follow-up

• How does the answer change if access to individual history events differs by role?

07Behavioral

Give an example where a clear invariant helped you make a difficult decision. Be precise about what you verified, who approved the tradeoff and which part remained outside your responsibility.

Explain a decision where correctness limited scope

Easy · Integrity · Ownership · Communication

Tell a truthful story about narrowing a feature, delaying a release or changing a design because the original plan could produce an incorrect result. Explain who needed the outcome and how you made the tradeoff visible.

Approach

1. Name the invariant at risk and your actual decision authority. A small example with a clear consequence is enough.
2. Show the evidence you used: a failing test, inconsistent state, user report or review finding. Explain alternatives and their costs.
3. Describe the safe result, remaining limitation and what you would do differently. Do not claim regulatory approval or clinical impact you did not personally establish.

Follow-up

• How did you explain the decision to someone who wanted the original deadline?

Veeva — Associate Software Engineer / Engineering Development Program

Additional reflection prompts

• Describe a data-quality problem you prevented or detected.
• Explain a technical choice to a stakeholder who cared mainly about a deadline.
• Show how you learned a language or codebase well enough to make a safe change.

Review your answer in three passes: check correctness, explain failure handling, then make the reasoning clear to another person.

08FAQ

Does the EDP process apply to experienced engineers?

No such generalization is justified. The cited posting targets recent graduates and candidates with 0–2 years of experience; experienced applicants should confirm their own assessment path. Veeva — Associate Software Engineer / Engineering Development Program

Why are the worked coding examples in Python?

They keep the algorithms executable and readable in this guide. The selected EDP posting permits Python for its initial challenge. Use the language allowed by your own invitation and rehearse its collection and error-handling semantics. Veeva — Associate Software Engineer / Engineering Development Program

Why emphasize versions and permissions?

Veeva’s Vault Platform material describes document/data management, configurable lifecycles and granular control tied to state and role. The exercises use these as product-context themes, not as a disclosure of interview questions or an exact Vault data model. Veeva — Vault Platform

Is latest approved the same as latest version?

No. A newer draft may coexist with an older approved revision. The exercise asks for the newest approved version, so it filters by approval before ranking. A real product must also apply its caller-specific visibility rules.

Are the practice cards taken from the current PracHub bank?

No. The public API snapshot contains one matching company-and-role question, which is accessible through the bank CTA. These seven cards are newly authored editorial practice and are counted separately. PracHub — public company and role question count

Does the document design prove a system meets a compliance standard?

No. It is a software-design exercise about identity, state transitions and evidence. Real retention, signature and validation requirements must be defined for the product and jurisdiction with the responsible specialists; do not invent those requirements in an interview.
