Applied through a referral.

I took a preliminary 15-minute HackerRank challenge, followed by a chat with the recruiter. Then, I was scheduled for a Skype interview.

I was prepared for data structures and algorithms, but I was asked a question on probabilities. I understand that, given my Data Mining Engineer profile, I should have probably expected a question similar to that, and I was ready to answer some theoretical questions. However, I did not expect I would have to code a question on probabilities.

I was sorely out of touch regarding programming for probabilities, and I screwed up my interview. The interviewer was helpful, but I was deflated simply by hearing the question.

I haven't heard back, but I have little doubt that this will be a reject.

A question on probabilities.

When you select a random index from the array, the probability of the element that is printed should be based on its weight.
