      Negative experience

      Application

      I applied through college or university. The process took 1 day. I interviewed at BluePi (Gurgaon, Haryana) in Sep 2017

      Interview

      It was a subjective paper consisting of 8 questions on coding and database queries. Around 100 students would be there. After giving the test, they hardly took 10-15 minutes to shortlist 6 students from a group of 100 students approx. It was really pathetic as i gave almost every answer to the question and one who was selected did half the questions in the paper. I think they shortlisted the student on an haphazard manner. It was really a bad experience due to there facetious criteria of choosing the students. Just advise to the company is that instead of calling such collosal amount of children and choosing in a very random manner, just invite few students and choose the best from them

      Application

      I applied through college or university. The process took 1 day. I interviewed at BluePi (Gurgaon, Haryana) in Sep 2017

      Interview

      Technical Question Paper consisting of 8 subjective type questions of Java. The experience was not at all good. There were around 150 students giving the subjective paper and they took only 10 mins to evaluate all the papers and only 2-3 people were evaluating the papers. Don't know how they can evaluate so many papers in such less time. Most probably they randomly picked up some people and interviewed them. They should not have called so many people if they cannot evaluate all of them. My advice is to not go for their interview as it is based wholly on luck.

      Interview questions [8]

      Question 1

      Implement a stack consisting of following functions : 1. Pop() - remove item 2. Push(item) - add item 3. Peek() - see last item 4. isEmpty() - return true if empty
