It took more than a month to complete four rounds of technical interviews and a coding test.

I qualified for the test and completed three rounds of interviews. After each round, there was a silence, with no information from the HR team. I wrote multiple emails, and then they scheduled the next round.

After the third round, HR replied to my follow-up email and asked for my current salary slips and details, stating I had completed all rounds. They mentioned that once their payment team gave clearance, they would provide an offer letter.

Here comes the twist: they scheduled another interview and never contacted me afterward. I wrote a follow-up email, and after two weeks, I was told I had not been selected.

Round 1: Coding test (2 Python programs and 1 SQL query).

Round 2: My current expertise and relevant questions on Data Engineering and Data Science.

Round 3: Data Engineering essentials, Python code to write, SQL query to write, DBA concepts, data warehousing, etc.

Round 4: Multiple Python pseudocodes, SQL queries, followed by tech questions and scenario-based questions.

Round 5: Conducted solely for rejection.
