Cervello Data Engineer interview questions

Two rounds. Had an amazing exposure to the role. The interviewer made it pleasant throughout the entire interview process. Although, I did not get the offer I was overall satisfied with the interview.

Cervello has the worst management of HR and staff who doesn't even have any courtesy to respond to any follow up mails. I got a call from one of their consultants about the position. He was very kind and helped me throughout the interview process. There were total 3 rounds - Technical, Culture Fit and Final Onsite interview. The onsite interview went really well and had positive hopes. After interview, for 2 weeks I continually kept sending follow up mails to the HR and never received any response. So, finally I ended up sending a mail to consultant who had approached me and he said that the position is filled.
