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.

Interview Preparation Tips

Round: Group Discussion
Experience: GD was conducted for shortlisted candidates and candidates were divided into groups of 6 people.There were 3 topics and each topic was discussed for 2 minutes.No specific rules,like each person needs to speak,are to be followed during the GD.Anyone can initiate,intervene,etc. Finally we were asked to link all three topics and this discussion went on for another 2 minutes.

Round: HR Interview
Experience: Only a single round lasting about 40-45 minutes.There were only 4 people in the panel and technical as well as HR questions were asked. First I was asked to go through my own resume, “Introduce/Tell us about yourself?".  E.g.:“Where have you shown leadership qualities?Have you led a
team?Size of team? What new initiatives did you take?”.Core questions starting form basics like “How does an airplane fly?” to specific questions about the different types of engines used in airplanes,their specifications, etc. were asked. HR questions were put up like"What was the most difficult decision in your life?" and grilled on my internship for 15-20 minutes which I did in Transocean. (Another oil field services company).

General Tips: You need to be very good in the basics of your
core courses and if you have done an internship in the oil industry,
you will definitely be grilled on that.Questions will be asked in quick succession.
Skill Tips: Highlight any intern in Oil industry or anything related to that in your resume.Any POR or any sport activity which shows your leadership qualities should me mentioned in your resume.
Skills: Leadership qualities, Athletic, Quick thinking, presence of mind
