I applied online and then received an email from manager in 5 days to schedule a 15 min interview. I assumed the interview to be just a meeting about getting to know me better (that is what the email said) I join the interview the manager starts talking about the role is not interested to learn about me. I tried to add those details when he asked me do you have any questions for me. Then he asked me 4 questions about robotics/coding. I could not answer 1 cause I have not used python threads (as I mostly code in cpp and that is my resume said as well). He ended the interview early, got a reject in 2 days.
