Interview Preparation Tips

Interview preparation tips for other job seekers - Strong at Data Structures and Algorithms, and good system design knowledge

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.
