Infineon Technologies Data Engineer interview questions

First round is a technical discussion with manager. She didn’t even listen to my intro as she is sending questions in the chat in the background . Not even listening to my approach. She got one answer in mind expected the same from me. I know it would be a bad experience right after 2 mins in the interview. She asked 3 sql and 1 pyspark code to optimize it, i have done 2 sqls and gave the code to her, she ran it in a compiler and said that code have errors due to syntax(mostly typos, logic is 100% correct) . One sql is to use a recursive cte to get the hierarchy of employees which i dont know, she didn’t even listen to my approach. And pyspark optimisation code, she is not ready to hear anything from me, before this interview in Infineon, I cleared 4 companies but this one I felt really bad that these kind of people do exist in the field

was called, and then tested live coding on the spot mainly how to access files and basic python scripts. Afterwards was asked a few questions on availability. Overall, it was quite smooth sailing
