Target Data Engineer interview questions

The whole Interview process took 2 weeks approximately. Round 1/ Get to know kind of meet up. A person working as Sr manager appeared asked overall experience in terms of technical. Some scenario based questions like - why do you want to join us, what do you know about target etc.... Round 2/ data structure algorithms like knapsack, two pointers and DP. Some basics of spark architecture. Round 3/ Mainly focused on end to end pipeline of my project. System design and comparison between services. Round 4/ It was again a technical round. I talked to many candidates who are working in target and they told me that you get selected after 3 rounds. But in my case they scheduled one more round and in this I got rejected.

The first interviewer talked about the job they are doing. Then he started asking random questions about everything that was not included in the job description. He asked about concepts from certain programming language, talked about nonsense. The second interviewer was rude and ended the interview quickly.
