I have applied for Technical support Engineer position Berlin,Germany location. First round was a Telephonic interview with the HR, 2nd round of interview was with the Manager,3rd was a Technical interview however out of 45 minutes of total duration interviewer explained me about the Docker company and its products and discussed about my work experience and responsibilities that i handled previously for almost 35 minutes.At last has asked me some basic questions approx 4-5 questions which i have answered him. Unfortunately i was not shortlisted for next round of interview. Even though i was informed that Docker and Linux experience is not required for this position from the beginning of the process but interviewer asked me 3-4 times at least do you know Linux basics and docker basics and i was not comfortable in answering him saying "NO" multiple times. I am really disappointed the way the technical round was conducted.
