Frequently Asked Questions about Software Engineer Interviews

How long should I prepare for a software engineer interview?

Most candidates need 4–8 weeks of focused preparation. Junior roles may need 2–4 weeks; senior roles can require 6–12 weeks due to the system design component.

What coding language should I use in interviews?

Use the language you know best. Python and JavaScript are popular for readability. Some companies prefer you work in the language of their stack — check the job description.

How important is LeetCode for software engineer interviews?

For FAANG and top-tier companies, algorithmic coding (LeetCode-style) is essential. For most startups and mid-size companies, practical problem-solving and code quality matter more than competitive programming tricks.
