      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Trell in Aug 2020

      Interview

      HR has contacted over phone and set up the interview schedule. There were total 4 rounds of Interviews. 1st Round: Machine Learning Basics, Deep into projects and work experience from Resume. 2nd Round (Assignment): It was a 4-hour live on-the-call SQL Assignment round. There were 7 SQL questions given and all of them should be answered and explained to the interviewer in time. 3rd Round (Assignment): It was a 4-hour live on-the-call Data Science Assignment Round. Dataset was provided and should build the complete pipeline from preprocessing to model prediction and should explain the whole pipeline to the interviewer. 4th Round (Managerial Round): Asked about the projects from resume and 3-4 simple logical coding questions to be explained. All went well but did not hear from HR even after several tries to get feedback. At least a positive or a negative feedback should be given.
