Deloitte Data Engineer interview questions

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.

1 interview round that took place in the Toronto HQ for the Omnia AI team consisting of behavioural cases along with a few technical questions regarding AI/ML & classification algorithms. There wasn't any whiteboard coding interview but this can vary depending on your interviewer. Typically, they just ask technical questions for you to explain verbally to see how you think. The interview lasted about an hour. I got a call back in 2 weeks with the offer in which I had about a week to decide if I wanted to sign.
