Interview Preparation Tips

General Tips: This interview was a technical one but was majorly a stress test. It lasted for about 1 hour 10 minutes. The interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B.Tech curriculum i.e. computer science related topics. He stressed a lot on the basics related to my project topic. Luckily I was able to answer most of the questions correctly. I tried to answer each question with examples and also used props on the table (like pens, paperweights, pen stands etc.) to explain my theories. It was my first offcampus interview, and I think I did pretty well for a fresher.
You need to stay calm and should apply presence of mind. Please go through the job description thoroughly word-by-word and recheck your resume to ensure that you are a best-fit for the position.

Interview Preparation Tips

Round: Test
Experience: Just 1 online test



Round - I (90 mins)



Online Test conducted @ HackerRank



a. M.C.Qs (Operating System + Aptitude + C Programming Language + Object Oriented Programming)



b. Programming (2 coding questions)The Online Exam started off after a brief Presentation on Amazon.





The MCQs were largely based on Operating System, Data structures and Algorithms, OOP concepts, C language and Aptitude.



Coding Questions



1. Determine whether a Linked List is a palindrome or not.



2. Given few sets of intervals print out the the entire intervals without overlapping , if they overlap then combine them into one.



Eg: Input : (5,7) (1 , 6) (2 ,4) (10 ,14) (8,9)



Output : (1,7) (8,9) (10,14)



Advice: Must solve at least 1 coding question to have a good chance for selection into the next round
Tips: CGPA holds importance because it is basic eligibility criteria for written test and then secondly it increases odds in your favor of your selection more than those with lower CGPA with same interview performance. Prepare a good resume



1. Prioritize your content



2. Put the most important information first (Academic Projects + Internship)



3. Proofread it twice



Advice : Do your best and leave the rest to god

Round: Test
Experience: Round II

Total Questions: 2

Round: Other Interview
Experience: Round III
1. Tell me about yourself
2. Project + Internship Discussion
3. Compress a given string "aabbbccc" to "a2b3c3"

Experience: Round IV
1. Internship Project Discussion (30 mins)
2. Find the largest count of 0s in a row in a matrix of 0s and 1s sorted in an ascending order row-wise.
3. Replicate a tree with random pointers inplace

Round: Other Interview
Experience: Round V
1. Question related to graphs involving concepts of Depth and Height of a tree. (Took a lot of time in solving it ! but finally recognized the pattern)
2. Maximum size square sub-matrix with all 1s
3. Find the median of an infinite series of integers
4. Find the most popular Google searches. (solved it using Trie and Max-Heaps)
2 more questions but can't remember them.Finally after waiting for more than 9 hours the results were announced and I was selected
Tips: Be cool and always ask the interviewer questions at the end of the interview. Explain the interviewer your progress while solving the question so that you both are on the same page + its easier for him to understand. Behavioral and H.R.
Tips
1. Speak clearly and with confidence
2. Always prepare yourself beforehand for some common questions like:
a. Tell me about yourself.
