How many rounds are there?

Usually 4-6 at product companies, sometimes fewer at startups and more at big-tech. The recruiter will normally outline the process up front.

Which round is hardest?

For most, machine coding or system design, they're time-pressured and open-ended. That's where targeted practice pays off most.

Frontend Interview Rounds Explained

Short answer

Most product-company frontend loops have 4-6 stages. Knowing the shape lets you prepare deliberately instead of guessing.

The typical loop

1) Recruiter screen - background, expectations and comp range. 2) Online assessment / DSA, JavaScript plus light data structures. 3) Machine coding - build a component or feature live. 4) Frontend fundamentals - JS, React, HTML/CSS, browser and performance Q&A. 5) System design - design a frontend (mid+). 6) Hiring manager / behavioural, experience, collaboration, motivation.

How to prepare for each

Map every round to targeted practice: fundamentals Q&A for the concept rounds, timed component builds for machine coding, a framework (RADIO) for system design, and 5-6 STAR stories for behavioural. Always have 2-3 thoughtful questions for the interviewer, it's evaluated.
