Deloitte Data Engineer interview questions

First there was a programming test (1h simple tasks in order to show your general understanding of programming). Then,the 1st interview was HR based but there was at least on more technical. In general, it was really professional.

I had applied through Referral. They responded and my interview was done within a week. 1st round- It went really well. The interview had immense knowledge in Big data. I waited for nearly a week for a callback. When I did not get a response even after dropping a mail to the HR, I contacted my friend who had referred me to check. He reverted with the message that my profile has been aligned for PySpark developer. Since there is no current OB in that, they pick my profile after OB requirement comes for the same. It's been 2 months, I have contacted the HR but didn't get any response. Tried all sources of contacting Deloitte. Nothing worked. My advice to Deloitte is that at least have a basic courtesy and professionalism to respond to the interviewees. We spent our valuable time for a reason.
