Take home assignment that took around a week to do. After I spent a week on the take home assignment I was disappointed to see that the interviewers did not spend any time taking a look at it and assumed I had not followed the requirements. I had to clarify that I had done it as requested. I was asked some standard behavioural questions followed by a hard LC question. They never got back to me after the interview despite several emails to my interviewers and HR.
