Perguntas de entrevista de vagas de Software Engineer - Machine Learning da empresa Celonis

Overall very bad experience. Lost time because after a long take home challenge, there is simply 0 feedback even though I asked multiple times for a feedback after the email. - 1st round, small chat with HR - 2nd round, 40 min chat with hiring manager, general questions - 3rd round, take home task. I have spent hours and completed the challenge. Hiring team didn't bother to send even a single line of feedback. Such an unprofessionalism.
