Interview
I made it to the 3rd stage of the process. I guess stage 0 is to have your CV be reviewed by the hiring manager. Then stage 1 is a written interview. Stage 2 was a General Intelligence Assessment. And stage 3 was a Python test provided by DevSkiller consisting of 3 sections.

Question 1
The python test included 3 sections. The first section had 25 multiple choice questions which required knowledge of built in libraries. The second one was a mathematical - programming problem. And the final section was a problem with string manipulation, which I didn't manage to solve in time.

Interview
Early stage interviews were composed of: Linux system skills, Python skills deep dive, and HPC skills back-to-back.
Following this there are interviews with directors and then offer. The early stage interviews were in parallel rather than next day interview with HPC meaning that you cleared the Linux and Python interviews.
