they shortlisted and sent online hackerrank test, after completion of test I followed up for the status which is non-usual, I applied for Data Scientist job in B'lore but got interview invite for Mumbai. Again post the follow up regarding job location, requested them to schedule the telephonic interview , but interviewer not showed up for 2 times , later clearing telephonic interview, they asked to come onsite. In onsite, HR was off on that day and interviewer came 45 minutes late, then few ML questions, but the interviewer was asking the write Math equation which is unusual interview for AI, then once came out of that immediately reception said you can leave , but interviewer said to wait. It is insulting. Then ,again I checked with interviewer about the status, he said you need to give another 3 more rounds of interview which is not mentioned in my mail. Thanks Much , good culture, keeping promise is very much important in organisation, apart from that having good interviewer who can statistics concept is much required then asking to write math equation . I don't mug-up the equation, prefer understanding the concept and building system from scratch . Thanks much for insult. Experienced and passionated people who work on research problem please don't apply.
