There were two rounds in total, the first round was general background discussion with manager, in the second round I was asked to present a case study on a kaggle dataset
I applied through other source. The process took 1 week. I interviewed at BILLA (Vienna) in Dec 2021
Interview
Interview was quite easy, the manager was nice and asked me mostly about my customer service experience and availability. Took little time and didn't have to wait for too long for a response
2 rounds one is resume and other technical round and there is one face to face interview first they send link to write assignment they will be qualify it you pass
