Received a call from a referral. The first round was a video call on Teams and was entirely technical and coding-focused. They asked me seven Python coding questions on HackerRank with live debugging. The questions primarily covered OOPs and design patterns (Singleton and other design patterns).

The second round was also a video call, but it was more difficult. More emphasis was placed on Linux core concepts. There were also questions on Python design patterns and general Python coding, as well as an in-depth explanation of automation frameworks.

Docker vs. VM (in-depth) Linux Boot Process Kernel Space vs. User Space Why use threading only? Why not multiprocessing?

Be prepared for in-depth questions on whatever you mention in your resume. They will take one point and ask for details. For example, regarding threading.
