As a Software Engineer at EQT, you play a vital role in building and scaling the technological backbone that drives North America's largest natural gas producer. Your work directly impacts operational efficiency, data management, and strategic decision-making across complex engineering and midstream assets. By developing robust software solutions, you help modernize traditional energy workflows, making operations safer, faster, and more data-driven. This position sits at the intersection of heavy industry and cutting-edge software engineering. You will collaborate closely with multidisciplinary teams—including reservoir engineers, operations planners, and data scientists—to translate complex physical challenges into scalable digital products. Whether you are optimizing compression systems, handling massive geological datasets, or automating production workflows, your contributions directly influence the bottom line and sustainability goals of the business. Expect a fast-paced yet collaborative environment where technical excellence meets practical problem-solving. EQT values engineers who can not only write clean, maintainable code but also understand the operational context of the energy sector. You will face exciting challenges in system architecture, data processing, and user-centric design, making this an ideal role for engineers who thrive when tackling high-impact, real-world problems.

PracHub editorial advice for the preparation topics above.
Brush up on SQL and data handling
Because many engineering workflows deal with heavy datasets, expect your ability to write clean queries and manage data flow to be tested.
Practice articulating your thought process
Interviewers value how you think just as much as the final answer, so narrate your problem-solving steps clearly and invite feedback.
Research the energy sector basics
Having a high-level understanding of how technology intersects with natural gas production or midstream operations will help you contextualize technical problems.
Prepare structured behavioral examples
Use the STAR method to organize your past experiences around teamwork, overcoming technical blockers, and managing tight timelines.
Showcase your curiosity
Ask insightful questions about the team's current technical stack, scaling challenges, and upcoming product roadmap during your interview loops.

Can you walk through how you would design an efficient SQL query for large operational datasets?
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.

- How does the query change if that join becomes one-to-many?
- What happens to this when the table is ten times larger?
Keep soft-deleted accounts from blocking re-registration
app_user holds user_id, tenant_id, email CITEXT, password_hash (NULL for SSO principals), email_verified_at, auth_version, status ('invited','active','suspended','deactivated'), created_at, updated_at, deleted_at. Two live accounts for one address inside a tenant must be impossible, but an address freed by a soft delete must be reusable, and the same tenant may delete and re-register it repeatedly. Write the uniqueness DDL for PostgreSQL 16, then the equivalent for MySQL 8 where partial indexes do not exist, and say what each permits once three deleted rows already hold that address.
Approach
- Start from what is actually unique: not (tenant_id, email), but (tenant_id, email) among live rows. PostgreSQL says that directly — CREATE UNIQUE INDEX app_user_live_email ON app_user (tenant_id, email) WHERE deleted_at IS NULL. A full constraint over the same two columns burns the address permanently the first time someone deletes an account.
- Keep case-insensitivity in the type or the index, never in the application: CITEXT as given, or UNIQUE (tenant_id, lower(email)) as an expression index where the extension is unavailable. A case-sensitive unique column is exactly how two accounts for one human appear.
- For MySQL 8 the predicate has to move inside the key: add a discriminator column that is a constant 0 while the row is live and is set to user_id on delete, with UNIQUE (tenant_id, email, deleted_marker). Live rows share the constant and still collide; deleted rows differ from each other and stop colliding.
- State the NULL variant and its dependency: leaving the marker NULL for deleted rows also works, because a unique index treats NULLs as distinct — true in MySQL, and true in PostgreSQL only under the default NULLS DISTINCT, which PostgreSQL 15 lets you reverse. Check the polarity against the three existing deleted rows: constant-on-live is what preserves the collision you want, and reversing it silently admits duplicate live accounts.
Follow-up
- A deleted account re-registers with the same address the next day. Do the old resource rows follow the new user_id, and how does the API keep the two principals apart?
- How do you honour an erasure request while resource_revision.actor_user_id still references this table?
