Recruiter screen, followed by a Code Signal coding assessment in the language of your choice. It was two easy Leetcode problems followed by two medium Leetcode problems. I completed 3/4 and that was enough points to get passed on to the final round, their "Power Day." The power day consisted of 4 parts: 1 behavioral, 1 case study, and 2 "technical." The behavioral asked simple STAR questions. The case study was similar to the process described on their website but easier, just walking through a simulation and doing some simple mathematical calculations. After that there was some code debugging. One round of technical was a data engineering system design interview, pretty typical to examples found on YouTube. The other round was coding answers to small problems in a programming language and SQL, all the tasks related to data engineering and databases in general. Overall, a pretty straightforward process. The interviewers were nice and allowed plenty of time for questions. The only downside was that they did not tell me the reasons I was rejected and what I could improve upon.

I wasn’t expecting coding for system design round but they asked me live coding in system design round as well . Prepare ingestion of data from multiple resources. And focus on pyspark and pandas
