Interview
I applied for a Frontend role and had an initial 30-minute discussion with HR over Zoom/Meet. After that, there was a DSA knockout round, which I cleared.
Following this, three interviews were scheduled: two technical rounds and one managerial/behavioral round.
The technical interviews were quite unique—focused on areas not typically asked in frontend interviews. They required fast problem-solving, strong familiarity with DOM APIs, and handling grid-based calculations. These are definitely areas that need specific practice.
The final round went average. I was able to discuss a partial solution, but due to time constraints, I couldn't fully complete it.
I was eventually rejected. I felt I performed well enough to move forward, but it seems every round needed to be near-perfect to progress.

Question 1
DSA question - need to create a recursively tree type structure.
On a sorting algorithm, we need to create a visual representation of the sorting algorithm in JS, where after each second we should see the elements shuffling in the array, and finally the sorted array.

Interview
30 min initial screening call with recruiter. 1 hour basic coding screening test. Then 3 interviews in a day that included 1 hour coding test, 1 hour system design test, and 1 hour behavioral interview, each one with a different set of people. Almost everyone was punctual and cordial but I don't think the system design test was executed in a way that could give any candidate a fair evaluation. I had a workable MVP for the question that was asked of me but didn't get a chance to develop it in time as I kept being interrupted by the interviewer asking me deep dive questions about what I was putting on the whiteboard. Got feedback from the recruiter who told me I did well in all the rounds except the system design and they thus decided not to proceed with my application.
