It was a pretty chill interview, though it depends on the interviewer. There were 3 rounds of technical interviews after one resume screening round. Make sure to include keywords and be truthful, as they will grill your resume in the hr round.

So, the interview had 3 technical rounds and then a HR round. I made it through the first two technical rounds, and my friends told me about the rest. The first technical interview was about 1 hour long and focused on Data Structures and Algorithms (DSA). I managed to solve the problem and its follow-ups. In the second round, they asked me to explain the architecture of a project I had listed on my resume. After that, I had to implement LRU caching, but I was really close to finishing but missed some edge cases, which is probably why I didn't move forward.

So, they shortlisted students straight up for the interview. It was a 4-round process: 3 technical rounds and 1 HR round. First round was mostly about my resume and one easy DSA question. Second round checked my problem-solving approach and included a medium DSA question plus some testing and optimization questions. The third round was a mix, with a medium coding question, resume questions, and some HR stuff. The last round was just HR. Everyone was super respectful and polite. It was a good experience overall.

My interview experience with this company was pretty bad and I wouldn't recommend it. The recruiter messed up our interview by not showing up, then started sending unprofessional WhatsApp messages and calling at weird times, and we never even settled on one way to communicate. During the actual interview, the recruiter talked in their local language during parts of it. After I heard nothing back for weeks and was basically ghosted, the same recruiter messaged me on LinkedIn to apply again. They also didn't seem to get what the job was even about. This whole disorganized process makes me think the company itself might be disorganized. It was a waste of my time and really frustrating, with no professional courtesy shown at all. Seriously, look somewhere else if you want a professional interview and clear communication.
