I applied online. The process took 4 weeks. I interviewed at Tiger Analytics in Mar 2024
Interview
5 rounds including coding round.
The HR discussion was terrible. The HR did everything in the HR discussion round except the actual HR discussion and finally, I was low-balled with an offer well below my expectation without any attempt to negotiate. Why would you ever consider someone as a candidate if your max budget is below their expectation?
Despite acing every round, I got rejected after the HR discussion for a very vague reason. The company may be a good place to work but the HRs are working very hard in not making it look like one. It's baffling to be rejected after the HR discussion round.
