Sartorius Field Service Engineer interview questions

Recruiter reached out about the position and I Interview twice over the phone. I connected well with the manager and informed we would move forward to face-to-face interview over dinner with another manager. I waited a week before reaching to the HR group but no response. I sent another email after another week emphasizing high interest in the position but still no response from HR. they basically ghosted me. as last attempt I contacted the recruiter and said they would contact HR directly but no response since.

The interview went on normal stages. Started with sending in recorded video for you to answer some general questions. then phone interview, and in person interview. Then, there is background check, drug test. online personality test etc. After hired, invited for training at a different location.
