Just for an interview for senior data engineer I

Looking for help on how to prep for the senior engineer I position, I know there’s a hacker rank assessment followed by two virtual interviews - one for technical problem solving including coding with python, pyspark and sql and the second is personal experience and case study

Then the second round is in person one expertise interview where you share technical projects and walk through data engineering fundamentals and the second is personal experience and another case study

What are your tips to pass these interviews and anything I should focus on to pass the hacker rank and the first round of interview? Any concepts I should really focus on?

Thanks in advance!
