Contacted on linkedin and had a quick call on the phone. It was a brief conversation regarding the job duties and pay rate. Ultimately it was not a good match for us but he was nice.
I applied through university. The process took 1 day. I interviewed at Sigmaways
Interview
2 Telephonic Rounds. One related to DS and Algo. Another one related to ML and Ai. The process was smooth and questions were moderately difficult. I was offered the internship in the end.
