Detailed description of the company's interview process:- First Round was Online Test with multiple ML+Python+SQL questions(Mostly ML). Crossed the round and then I was called for Face-Face Interview at their Location on 25-Sept-19 . It happened to start at 2:00 PM but included a lot of waiting without any information when its going to get start. Finally HR came and introduced me with 2 interviewers. Interview went for good 45 min -1 hr. Interview round was good. They asked many questions back to back of ML concepts, some python questions, to derive certain formulas. Second round went very well , I gave all of their answers and they were certainly very impressed with my knowledge of knowing the concepts in deep. The second round ended and after waiting for almost an hour again, HR came and told me they had certain different expectations. He added candidate should be well versed with Stats, Python, SQL, ML concepts, etc. I told him i am good in all of that and that's why was able to cross the 1st round & second round too went pretty well. After that with confused tone, he told me that -'I was selected for the second round' too. And then he asked me to call him after 1 week to schedule the third round. First of all it was very confusing because that's the HR work to schedule the interview and inform the candidate about the same. Even I was selected for the round, he had no good expressions on his face and found him pretty rude and confused. After that i went back with this confusion(Travelled more than 50 kms for this round). After 1 week I called him for the third round as asked by him, he asked me to call some other day. I again called him the day he asked me to call and then he told me , he will get back to me, but he never did. I again called him 3-4 days later to know about the status of the process. He told me that next day their will be telephonic interview in between 12-2 pm. I waited the whole day and called him the next day, that panel didn't call me. -He told me that he will get back, but again he didn't call me. - I called the staffing agency-IBST the other day and told her this whole scenario. She told me that no one got selected that day. I again told her that HR himself has told me clearly that i was selected for the next round . She was also confused and had no information. - After that i stopped calling this careless HR and lady from IBST. Have some shame to waste the candidate's time and money. I gave around 20 interviews and interacted with multiple HR's. But this one was the worst experience. They kept me in confusion for a month(involved a lot of calling from my side, in which HR kept saying he will get back to me). Atleast have the courtesy to clearly tell me your decision, whether to take my candidature forward or not. Extremely unprofessional HR who had no respect for the candidate he is selecting for the organization who can be his potential employee. Totally wasted my time and money for this company's Interview process. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
