Average Interview
This company came to our college for the placements . They offered internship with the possibility of Pre-Placement Offer (PPO) of 8 lpa. I interviewed at Betsol.
Process :
The selection process was very simple . Basically there were three rounds for the selection.
1 . Multiple choice round : 40 questions , 30 mins - In this round various objective type questions were asked. These all questions were related to Operating system , Database management system , Data Structures and Algorithm , Computer Networks and programming language concepts etc.
2. Technical round : 1 hour - This was technical interview round . In this round questions related to Data structure & algorithm and Database management system were asked. The interviewer was quite good person. He helped me when I stuck at some point during the interview . He gave me some hints to write the efficient code for a problem. He started the interview with very easy questions then started asking tough questions.
Questions :
1. Definition of linked list , it's properties and applications
2. What is the basic differences between an array and a linked list ?
3. Why multiple inheritance not possible in Java whether it is possible in CPP.
6. Can you implement a stack using two queues ? -> In this question he gave me some hints. At the end I was able to write and run the program successfullly.
7. I was given an array , it was an sorted array with duplicate entries . I had to write a rogram to remove all the elements with single occurence . Once all the elements of single occurences are removed only the duplicate element remains in the array. The next task was to take only value . For example if we are given an array .
arr = {1,1,3,4,4,5,5,5}
After first step arr= {1,1,4,4,5,5,5}
After second step arr= {1,4,5}
Time complexity and space complexity and why ?

3. Managerial round : 30 mins - I was able to clear the technical round of the interview. Next round was manager round . It was my first managerial interview so I was little bit nervous. But the manager was too good , he started the meeting with introduction , then some hr type questions and then a DSA problem .
Questions :
1. The first question was tell me about yourself ?
2. What is the reason you want to join our company ?
3. What are your strengths and the weakness?
4. DSA question : He gave me an array and asked me to find out the first subarray whose sum is equal to the given sum . I suggested two solutions of the problem. I told him how both the solutions are different . I explained him the time complexity of the problem . He was very much satisfied with the solutions.
{1,2,3,4,9} , 7 = { 1,2,4}
