Every company is different, just like every person. But based on my experience as senior software engineer interviewing (both as candidate and as a hiring manager) over the past three months (big tech and startup), I've noticed two broad categories:

1. Traditional Big Tech Interview Style

A LeetCode-style coding exercise during the phone screen, followed by an onsite consisting of a mix of system design, debugging, additional LeetCode problems, and behavioral/product interviews.

2. Early-Stage Startup Style

Start with a coding homework where you're expected to build using agentic coding tools. The interviewer expects a fully working prototype, along with thoughtful design decisions and trade-offs. Note that for manager/director level hires, homework is usually a ppt presentation. Onsite completely depends on who is the hiring manager, different not just on company but on who is the hiring manager.

Early-stage startups seem more interested in seeing how you use AI agents to build real software, rather than just how well you solve isolated leetcode problems.

Hope this helps!
