Was asked very weird questions about my favorite machine learning algorithm or methods for data engineering. When asking for what kind of problem they were trying to solve they just reiterated the questions. When suggesting different solutions it got really technical, which I was not well enough prepared for. So definitely go deep into the theory if it's for a data related job and know at least 1-2 algorithms by heart.

Panel with two interviewers. No hard questions really, but it was obvious that just knowledge of data science wasn't enough to get the job. What they mostly asked for was CI/CD pipelines and Version Control with Git etc. Moreover, some kind of big data knowledge (for example how to handle Tera of data with MySQL) was essential.
