Steps:- 1. Cocubes Assessment (from Home): Section A: Online exam, consisted of MCQs on quantitative aptitude, logical reasoning, English comprehension based questions. Section B: 3 Coding questions- a)Calculate work=force*displacement b)Calculate Euclidean distance of 2 points from origin c)Add 2 numbers that are given in the form of a linkedlist 2. HirePro Assessment (onSite): Section A: MCQs on quantitative aptitude Section B: MCQs on english comprehension and logical reasoning Section C: 3 Coding questions- a)Remove duplicate characters from the string, ignoring the spaces b)Given a sequence of numbers in the form of string, tell if it's all increasing (nth number is greater than (n-1)th number) , all decreasing or random c)Given an NxN matrix (N=odd) find the diamond with the largest sum 3. Technical Interview (onSite): * Interviews were focused on 3 things: CN, OS, DSA, OOPs * Depending on the interviewer you may get more or less questions from the above subjects * From CN, and OS expect standard questions from college syllabus * From OOPs you will be expected to associate with real life examples * When preparing, don't just see what a certain thing is, but also see why it has been done in that particular way For DSA you may get easy questions like find all the subsets of an array, rotate a matrix, reversing a string, or maybe standard questions on LinkedLists and Trees (check this link) 4. HR (onSite): It was conducted in parallel with the technical interview, like you come out of that and after a few minutes you will be called for HR. Nothing special for HR round, just a casual talk with candidates. Important points: * You should be quick in your aptitude so practice beforehand * Ask the candidates before you what they were being asked in interview, you will get common questions * If your interview turn is at the very end, chances are they have already made up their mind about whom to select and your interview will be just a formality. (In our case, the very last person was asked questions from DBMS and many were not even called for HR round) * If you are not called for HR round, it means they have rejected you. All the best!
