As a Software Engineer at VeriPark, you will join a global team focused on delivering high-impact digital transformation solutions for the financial services industry. VeriPark specializes in building sophisticated banking, insurance, and customer experience platforms, meaning your code directly influences how millions of users interact with their financial institutions. You are not just writing features; you are building the digital backbone for complex, mission-critical financial systems. The role demands a balance of technical rigor and business awareness. You will work on projects involving CRM, customer engagement, and digital banking modules, often navigating the complexities of large-scale enterprise environments. Success in this role requires a candidate who can translate abstract business requirements into clean, scalable code while maintaining the high-security standards expected in the financial sector.

PracHub editorial advice for the preparation topics above.
Own your CV
Be prepared to explain every line on your resume in depth. If you list a technology, be ready to answer advanced questions about it.
Communicate your logic
During coding tasks, speak aloud. The interviewer wants to know how you think, not just if you have memorized a solution.
Focus on the fundamentals
Don't get distracted by niche tools. A deep understanding of OOP, data structures, and algorithms will serve you better than surface-level knowledge of many frameworks.
Prepare for management rounds
Do not neglect the non-technical interviews. These are critical for determining if you are a good long-term fit for the company.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.
Solve a standard algorithmic challenge (e.g., FizzBuzz or string manipulation tasks).

Approach
- Restate the input: its shape, its size, and what is guaranteed about it.
- Name the brute-force solution and its complexity before improving on it.
- Choose the data structure from the access pattern, not from familiarity.
- State the target complexity and say which constraint rules the naive version out.
Follow-up
- How does this change if the input no longer fits in memory?
- What is the worst case, and how likely is it on real data?

How would you optimize a query that is performing poorly in a database?
How would you optimize a query that is performing poorly in a database?
Approach
- Name the grain you start from and join outward from it.
- Check whether any join is one-to-many before aggregating, or the sums inflate.
- Say which index the query would use, and what makes it unusable.
- Handle the rows that do not match: that is usually the actual question.
Follow-up
- How does the query change if that join becomes one-to-many?
- What happens to this when the table is ten times larger?
Denormalise tenant onto revisions and backfill it live
resource_revision (revision_id, resource_id, version, actor_user_id, change_kind, patch, request_id, created_at) has 400M rows and no tenant column; tenant_id lives only on resource. Two reads need it: a tenant-scoped audit feed ordered by created_at DESC, and an offboarding purge. Both join back to resource today. Justify adding tenant_id to resource_revision against those two reads, name the anomaly the copy introduces and the constraint that prevents it, then give the ordered migration for a live table taking 1.2k writes/second — the lock each step takes, how the backfill is batched, and where each step stops being reversible. PostgreSQL 16.
Approach
- Justify from the access path rather than from taste. Without the column, the audit feed either scans resource_revision by created_at and discards other tenants' rows, or resolves the tenant's resource_ids first and probes with them — both proportional to the tenant's whole history rather than to one page. With (tenant_id, created_at DESC, revision_id DESC) it is a seek that stops at 50 rows, and the purge becomes a ranged delete instead of a join.
- Name the cost exactly: a second copy of a fact can disagree with the first. Make the disagreement unwritable rather than documented — add UNIQUE (resource_id, tenant_id) on resource so it can serve as a foreign-key target, then FOREIGN KEY (resource_id, tenant_id) REFERENCES resource (resource_id, tenant_id) on the revision table. A revision can then only ever carry its parent's tenant.
- Step one, expand: ALTER TABLE resource_revision ADD COLUMN tenant_id BIGINT NULL, with no default, so it is a catalogue change and no rewrite. It still needs ACCESS EXCLUSIVE for an instant, and that instant queues behind the longest open transaction on the table while every later query queues behind it — set lock_timeout to 2s and retry rather than wait.
- Step two, dual-write: deploy the writer that populates tenant_id on every new revision while reads still use the join. Reversible by redeploying the previous build, because nothing reads the column yet.
Follow-up
- The backfill is half finished and a rollback is required. What state is the table in, and what does the previous build do with a half-populated column?
- How do you verify the backfill actually finished, given rows are still being inserted while it runs?

- Clarify what is being asked and what a complete answer contains.
- State your assumptions explicitly before working the problem.

- Work from the requirement backwards to the design.

Can you explain how you would approach debugging a complex issue in a legacy codebase?
Approach
- Establish what changed and when, before forming any theory.
- Pick a bisection that eliminates candidates whichever way it turns out.
- Check the instrumentation before believing the symptom.
- Separate the trigger from the cause; the deploy is rarely the bug.
Follow-up
- What would you look at first, and what would it rule out?
- How would you tell a cause from a coincidence here?
