What a technical interview may involve
The format varies by company and level. You may see a coding exercise, a debugging prompt, technical questions about projects, or a discussion of tradeoffs. Read the interview invitation closely and ask the recruiter what format to expect.
Build the fundamentals
Study the programming language you will use, core data structures and algorithms, and the reasoning behind time and space complexity. Practice coding problems separately; an interview simulation is not a replacement for deliberate problem-solving practice.
Explain while you solve
Before writing code, restate the problem and ask a clarifying question. Narrate the tradeoff between a simple approach and a more efficient one. While debugging, describe the hypothesis you are testing instead of silently changing code.
Discussing technical projects
Prepare one project in depth: architecture, key constraints, a tradeoff, a bug or failure, and what you would improve. Focus on your own contribution and avoid turning the answer into a technology list.
Preparation checklist
Combine coding practice with one spoken rep. Review a project explanation, practice a debugging walkthrough, and use a mock interview to hear whether your answers are clear under time pressure.
- Confirm the interview format
- Practice fundamentals and coding separately
- Prepare two project walkthroughs
- Rehearse technical explanations aloud
- Review one feedback report and retry one answer
