  • Q1. Hashmap working
  • Ans. 

    Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.

    • Hashmap uses a hashing function to map keys to indices in an array.

    • It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.

    • In Java, HashMap is a commonly used implementation of the Map interface.

Interview Preparation Tips

Round: Test
Experience: The first round had two sections. First section consisted of general aptitude and technical aptitude questions. In the second section we were given one coding question, for which we had to write the code in a language of our preference (C,C++,Java). Around 20 students were selected in the first round.

Round: Technical Interview
Experience: The second round was a technical interview. Two interviewers were present and the interview duration was 1-1.5 hours. Questions on Computer Networks, Databases, Operating Systems, Algorithms were asked. But they were more concerned about coding fundamentals especially C++ and Java. 6 students were selected in the second round.

Round: Technical Interview
Experience: Third round was again a technical interview. The interview process was same as previous second round.

Round: HR Interview
Experience: All the 6 students who were selected for the third round had a HR interview.

General Tips: The technical interview process was exhausting as the interview duration was 1-1.5 hours and challenging as they asked questions from all major fields of computer science.
Skill Tips: Prepare a decent resume and have at least 3-4 hard copies of it available with you all the times.Also do carry passport size photos with you. While going for interviews wear proper formals,carry 2-3 copies of resume and a pen.

Interview Preparation Tips

Round: Test
Experience: The questions were tricky. We were given a paragraph and after reading it, a statement was given to us and we were asked to say if it is true, false or cannot say. The structure of the statement put us into a a tough place. So practice of such kind of questions is necessary.

For data interpretation questions a good hand on basic statistical mathematics is needed. One has to be quick because of the time crunch. The questions were approachable

Round: Technical Interview
Experience: In this round my resume was scanned and I was required to speak about myself, my projects and explain certain areas of my resume. The interviewer picked up one of my basic project, surprisingly, and asked me to elaborate on it. He asked me how I can improve the project. And I had to write a code to make that change. Basically, one should have a good idea about the projects they've done/ mentioned in their resume. And know it in detail.

Few questions on data structures. Prepare well for coding type questions and data structures.

Round: Puzzle Interview
Experience: The interviewer asked me two puzzles. They were moderate level. And also luckily he was helpful whenever I got stuck.

Round: HR Interview
Experience: HR round was good. Basic questions like " tell me more about yourself", brief information about my past history, college life, extra curricular activities. In the end she asked me, "should we hire you?" And I lightly answered " why not!" So it was a good interview overall.
