One of my friend referred me and I was contacted the same day over phone and was asked if I was free to take a Language (German) written test. I told I was fine and in an hour HR sent the question paper and I was asked to get back with the answers in a day. The questions were decent any could be answered by anyone who has completed B1 in German Language. I was through the Language round and in the next 3-4 days I was asked to take a face to face interview on Video call, that also was a language test where the interviewer asked me some basic questions about me and I was asked to describe myself and a few questions were based on that, all of the above was in Deutsch. I cleared that round and next was a written test, Aptitude, English and Reasoning. I cleared that as well and the last round was ops round and this is where it got a little tricky as the interviewer tests ur patience level and asks u some tricky questions but everything is about u and what u tell. So nothing Technical or Aptitude questions, he only asked who is the vice president of India as I told I was good at quiz and aptitude. And I cleared the final round and the HR got back within 4-5 days and told me I had made it through. I was asked to join after 20-25 days and HR sent me the offer letter the same day after discussing some basic things over phone.
