The first round is a simple introductory session where you mention which stream suits you.
The second round is an online coding assessment consisting of 2 sql and 1 python questions. These were easy.
The third round is a video interview(technical) with an engineer. This was the worst part of the process.
1. I was not even provided a data file. I had to copy the data from a link and put it in a file, format it as the format was horrendous.
2. Then I had to import the data file into a SQL database. I was not even mentioned the kind of IDE to use as they differ very much for SQL and Python.
3. Finally I had to solve the problem. All in 20 minutes. It felt like shooting in the dark! Worse, I was able to solve the problem in 10 minutes after I had set up a local PostgreSQL instance in my Mac.

For me it was first general introduction which went fine and then they immediately invited me for the next step, which is coding where you are not allowed to take any external help includign Google. This step also went fine, cause I was gridning SQL and python. I got 2 SQL questions, quite easy and an algorithm, which I completed but with not the optimal solution. Still got a callback for the third interview, which is live coding, it requires to have the environment ready, According to my interviewer I'm about to expect data-related problems which I should solve with either Python, SQL or PySpark. That's all that I know so far.

-> Screening (just to know you, ask about your experience, etc.)
-> Problem solving (1 SQL problem, 2 Python, first one was to regarding characters in string, second one was to solve a bug in already Python code)
-> Live coding (so far in the email he has just mentioned to setup both Python and SQL setup)
-> Project (no clue right now)
It was a 3 or 4 stage process which has various types of interviews. One among them pre screening round, and another is online test, and one more is video interview, etc
