ZeroCodeHR Product Implementation Analyst interview questions

It was an on campus drive, there were three rounds: Aptitude, Group discussion, HR interview. It was started around 10 am and lasted till 8 pm. and the next round was technical interview that was supposed to be at the office but due to some reasons they've postponed it. And finally when they called us after almost 3 weeks, they called us just for the sake of calling they had no intention of hiring, they were not at all serious and they interviewed us while they were working and were giggling at the same time, unprofessional . And they said the company was hiring for Implementation analyst role but they conducted the interview for rnd role. There were again 3 rounds at the office in-spite of completion of 3 rounds at the college and out of 21 who got shortlisted for the interview at the office, no one got selected for the next round. Do not waste your time by visiting the office, they conduct the interviews for the sake of time-pass.
