I interviewed with Compro Technologies, New Delhi for the role of Associate Software Developer.
There were a total of 4 rounds –
1) Online Aptitude and Technical test by Talentgrids
This was a test conducted by talentgrids on meaZr.com. There were about 60 questions filled with aptitude, logical, reasoning, C/C++ output questions, DS, Algo etc. The time limit was 60 minutes. Output questions were very tricky so practice C/C++/Java output questions.So, the best thing to do is to attempt easy ones first, like output questions and other knowledge based questions. Do the difficult analytical/reasoning questions later on when you have time.
2) Skype interview
There was a Skype interview 3-4 days after students were shortlisted. Basic questions were asked by interviewer like C++/Java difference, the meaning of various keywords in Java, OOPS concepts and what all you have done in programming/projects.

1. Practice as many puzzles as you can from the internet. They have a booklet and from that, they will ask you puzzles of various difficulties.
3. Practice DS questions and some algorithmic concepts. Practice LinkedList, Arrays, Stack, Queues, Trees. They won’t ask in depth but at least make sure you are aware of all the common interview questions on DS Algo.
GeeksForGeeks was a great help in preparing puzzles and DS concepts. All the best for your interview!
