A complete waste of time going onsite! Got a mail from the recruiter for a "Group-coding" challenge for the SDE position. The challenge starts at 10 in the morning after a brief about the company. The problem was about scheduling ads using Amabot where the problem divides into 3 1. Scheduling, 2. Validation, 3. Optimization. It took about an hour to decide the who takes what and understanding the problem was really hard although the API was given. Then came a discussion with the developers about the problem and that lasted for half an hour; noon over. Two hours later another discussion about the problem where I found out that I had made a mistake in the logic. Bid adieu for my hopes in the evening. An advice to the fellow interviewees: Please avoid this format of interviews as this does not completely reflect the kind of problem solving capability and opt for one on one where an interaction will make the problems to be understood.
