MakeMyTrip Java Developer(Fresher) interview questions

It had 2-3 rounds one was online which comprises of technical and aptitude questions(from home location only). If one clears it then they will call for technical interview. Now the catch I was being called for interview and interview was not been conducted (@gurgaon HQ).their were around 10-12 candidates and they collected resumes from all of us and called one by one on random basis.Each interview was for 10-20 minutes.When the last 4 candidates were left(I was among them).They called 4 of us together gave a terrible Question and 15 min time to solve that.Then abruptly they came after 5 minutes and said time over and collected our sheets.we were waiting for our results(in our case interview was conducted like a bad joke).We were waiting from 1PM to 6 Pm and they said Go home we will inform you. Highly unprofessional and partial
