What to look for in a Software Engineer

1

Engineering, not just coding

Ask how they think about design, testing and maintainability, not just getting it working.

2

Problem-solving depth

Give a real problem and watch how they reason, not whether they know the trick.

3

Collaboration

They review code and mentor. Look for someone who lifts the team's standard.

How to run the hire

1. Define the level and domain
Be clear on seniority, stack and the kind of systems they'll build.

2. Use a realistic exercise
A design discussion or practical task beats abstract algorithm puzzles for most roles.

3. Source and approach
Approach passive candidates directly - the best rarely apply.

4. Assess reasoning
Pair on a problem and listen to how they think about trade-offs.

5. Reference impact
Confirm they raised quality and delivered, not just occupied a seat.
