Groww Software Developer interview questions

There is an OA round having two questions of DSA, one is of medium difficulty and another one of medium to hard level. I solved both of them out of 100 students 16 are shortlisted for interview. The interview has two rounds one is the DSA and problem-solving round and the other one is the HR round.

I applied online for the role of BE Engineer. The interview process involved 3 rounds. DS/Algo, Machine Coding and Hiring Manager round. After the second round, I got a positive feedback from the HR who said that we will be moving on to the hiring manager round. When I did not receive an invite for the next 3-4 days, I called the HR who told me they are again doing an analysis again of the first 2 rounds. The next day when I called back to check the status, I was told that the feedback from the panel was negative. My friend who applied for FE also got rejected in a very similar fashion. A company should be more transparent with their process.
