Technical Behavioral
The interview had a few rounds, mostly focused on technical questions. The interviewers were really nice and polite. Even though I don't think I nailed every part perfectly, I still got an offer. I guess they don't expect candidates to know and solve everything.

So the HackerRank interview is like, 90 minutes long and you get 3 questions. The first one is about using CTEs and table joins in SQL. The second Python question is all about groupby, sorting, and how to mess with time series data using Python. Basically, they wanna see how well you can write SQL queries, especially with CTEs and joins, and if you can handle data manipulation in Python like grouping, sorting, and working with time series stuff. It's all about checking your problem-solving, SQL, and Python skills in the time given.

Technical Coding
I had a technical round, which went pretty great. The interviewer was super helpful, as I was not prepared for the use of pandas and python. The interview process is not too organized because I expected sql, python and technical questions. Later there was a take home assessment which was all correct.
Confirmed questions1 question
- Have you ever used pandas in Python?
