Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms. eBay interviewers were not much concerned about the resume but they would surely browse through it and ask you questions from it. So it’s better to write genuine stuff rather than bluffing about things you have not actually done.

Round: Test
Experience: The first round was the written test. The test consisted of two sections one dedicated to the programming questions and the other to the logical reasoning questions. The paper was tough or so to say very unique. The programming questions were based on stacks and queues. One question was asked on circular queue. In logical section one of the questions that I remember was to derive numbers from 1 to 10 using only 4 four’s with the help of any of the mathematical operations. Other logical questions were more or less similar to this. There was also a general aptitude section which was comparatively simpler.

Round: HR Interview
Experience: This round was an H.R. interview round.He reviewed my resume and asked me some questions based on that. It was sort of a stress round as the interviewer was pushing me for answers.

Round: Technical Interview
Experience: In this they tested my programming and data structure knowledge. In data structure I was asked that, if there was a duplicate entry in a given link list then how would I find it. He also asked about the virtual functions and exception handling. He also inquired about the project that I had worked upon – I walked of a coding project in which I had used some unconventional algorithms.
Tips: Good knowledge of data structure and database management may prove helpful. They are more concerned about your knowledge. If you are good at web coding then it is always an added advantage.

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms. For any software company in general, do mention all software projects you have done and languages/software packages you know.

Round: Test
Experience: The first round of the selection process was a written test which comprised of two sections. The first section had aptitude based/puzzle based problems. Questions were tricky and didn’t require any calculation. Some of the questions were
1) Form all numbers from 1 to 10 using four 4’s and the basic arithmetic operations +,–  ,* and /. 2) Pick the odd one out from a given series. 3) Complete the series (a series with the starting alphabet of days in a week was given). 4) How many knights can you place on a standard chess board so that no piece can attack any other piece? Subjective answers had to be given with proper explanation for the same.
 The second section was based on C/C++ programming. There were three questions. The first one required the candidate to write the output of a given program. The next question was based on simple if-else statements while the last question was based on circular queues. All questions in this section were easy if the candidate has decent enough programming skills.
Total time for both the sections was 1 hour. There was no marking scheme and short listing was done based on the overall response of the candidate. Some particular questions or parts of questions, however, were considered more important by the company, and candidates answering those questions and a few others correctly, were shortlisted for the next round.

Round: HR Interview
Experience: The first round was a 1 to 1 interview wherein the interviewer tried to put me under pressure by pointing out mistakes in my answers to written test and making me solve the questions which I had not attempted in the written test. He also asked me about my family background, why I think I should be shortlisted for the next round etc.

Round: Technical Interview
Experience: The interviewer asked me about the programming languages I had worked on. No question was asked from languages other than those I mentioned. There were some standard questions about data structures and their implementation using C++. As I had worked on a couple of websites, the interviewer asked me questions related to HTML/CSS/PHP/MySQL/JavaScript. I was also asked to show one of the websites I had designed on the internet and the interviewer asked me a few questions about it. Except for a few, questions were very basic and easy for someone with good programming skills.

Round: HR Interview
Experience: The final interview mostly had HR questions. The interviewer talked at length about my interest in sports, my favourite sportsman and why. He also questioned me regarding the websites I had worked on, other extracurricular activities and what did I learn from them, what do I know about eBay and how would I be able to contribute to it if I am selected.
Tips: Revise programming concepts. Do not panic even if the interviewer tries to put you under pressure.

College Name: IIT ROORKEE
Motivation: EBay is a renowned company. I didn’t have much idea about the job profile on offer. However I did know that it was in the field of website and software development. I also found a lot of information about the company through the company’s Wikipedia page.

Interview Preparation Tips

Round: Test
Experience: There were around 10 MCQ questions and 3 coding questions. Quantitative ability was tested in MCQs and programming and algorithmic skills were tested in coding questions.
Tips: Don’t try to over-optimize your algorithms if time doesn’t permit. First write a pretty decent algorithm. You will get through the written test. After that, try to optimize your algorithm only if time permits.
Total Questions: 13

Round: Technical Interview
Experience: Questions on basic data structures of Computer Science. Basic tree algorithms with coding. Some analytical questions.
Tips: In all the interviews, try to be as confident as possible. Sometimes they will just see your confidence and they will take you through that round. So be confident and be happy.

Skill Tips: CGPA > 7.5, decent algorithmic skills and coding skills, good analytical skills. No computer science in-depth knowledge is required. They didn’t consider any extra-academic involvement. Maths ability such as probability was required. Quantitative ability was required in Written Test. Proficiency with any programming language was enough. You should be able to explain your BTP project in full details. For internship, apart from project related technical knowledge, you should have an idea of the business relevance of the project. Try to prepare with people giving CAT. This will help enormously.

Interview Preparation Tips

Round: Test
Experience: First round was a simple round which involved 10 multiple choice questions and 3 coding questions on hackerrank platform.

Round: Technical Interview
Experience: Mainly on topics like networks, data structures and algorithms, operating systems. The interviewers looked for people who have had prior experience in web development and asked questions regarding web development in depth too.
Tips: I recommend everyone to read the book titled, 'Cracking the Coding Interview' as it was helpful in my approach to an interview.

General Tips: The one major thing that would give you the edge in joining Myntra would definitely be exposure to web development. Since it is not a part of the curriculum , it's all the more important for you to familiarize yourself with web development. In fact, a few projects in the same field would put you in a very advantageous position to get the job.
Skill Tips: 1. Start your placement preparations well ahead, no point regretting later.
2. Keep a concise resume. Do not take your resume to several pages.
3. Do not neglect aptitude preparation. Many people do this mistake and end up not clearing the first round for several companies.
4. Be thorough with your basics across all subjects. (Do not neglect any subject, even they you may like a few and dislike the others.)
5. Keep in mind, the interviewers are really friendly and try to make sure that you're not nervous during the interview. All they want to do is to test you. Be confident and give it your best shot.
