GWF MessSysteme interview questions

At first they contacted with me via telephone and after this first touch, they told me to proceed with a technical interview. Regardless the fact that I misunderstood the way this interview would take place, because ultimately it was an evaluation test, this test was difficult with a very restricted duration (approximately 20 minutes). It consisted of about 10 questions with one of which requiring Ltspice, for which I was not informed.

First I did an 6 hour test for sql, flow diagrams, logic etc.. Then a technical interview which I was asked sql and python questions. Also asked about the big-o notation
