Interview Preparation Tips

Interview preparation tips for other job seekers - Answered almost all questions but still the interviewer gave feedback as, cannot write pyspark code. Although there was only one pyspark coding question and I did it.
In fact interviewer turned camera off several times between and missed responding for a few seconds.
He even didn't tell me to share screen to see what I code.

Totally not serious about the interview..
