First, we give you an assignment to see what you can do practically. Then, there's a screening to see if you're a basic fit. After that, a technical interview where we check your problem-solving skills and what you know about the domain. If you pass that, you'll have a managerial round to see how you communicate and if you fit the culture. If everything goes well, we'll make an offer.

Coding Technical
So I applied through campus placement. After an initial shortlist, they gave us a programming task to develop an API. Based on that, they shortlisted us for the technical interview. The technical interviews for some of us were based on our projects, but for others, it was just normal DSA questions. So, not everyone had the same type of interview.
