Never got to the interview. They rescheduled 5+ times/were no shows at every interview I attended and claimed it was technical issues. This was all for some program where they train you to be a data engineer but it seems like they couldn't figure out an interview
it wasn't too difficult; there were about 3 rounds. There was an online assessment which included a multiple choice for technical and recorded video prompts for behavioral. Then there was an HR screening call and then technical interview with someone live.
In the technical interview, they asked how technical strong I am with lots of scenario based and straight away questions. In the second technical round, they asked about deep technical knowledge.In hr discussion they asked about of I am willing to work on any shift and okay to relocate to any city based on project requirements. After offer negotiation, it was complete
