Interview Preparation Tips

Professional and academic backgroundI completed Computer Science Engineering from JAYPEE INSTITUTE OF INFORMATION TECHNOLOGY. Eligibility criteriaNo criteriaGrofers interview preparation:Topics to prepare for the interview - Data Structures, Algorithms, Dynamic Programming, OOPS, Computer Networks, Operating systems, DMBS, System Design, Python, DjangoTime required to prepare for the interview - 6 MonthsInterview preparation tips for other job seekers

Tip 1 : Practise Data Structures and Algorithms as much as you can on daily basis. Don't Fix numbers in your head, but practise as much as you can from all topics on daily basis.
Tip 2 : Give Programming Contests on a Daily basis. As it helps you to think of any particular problem in the fixed time frame.
Tip 3 : For Mastering DP, Learn From Aditya Verma Youtube Playlist and apply around 100 questions for solving any DP problem.
Tip 4 : Also Learn Computer Science theory subject once a week so that you will have a deep understanding of the particular subject since many interviews grind on CS theory subjects like OS, DBMS and Networks 
Tip 5 : Make at least 2-3 Projects in any technology you like maybe Web Development or Android Development. It shows that you have some experience in Development and the company don't need to waste time on you for teaching frameworks.
Tip 6 : If you have time learn some System Design and learn how to design any system from end to end. Especially learn about designing a database of any application. In many interviews, the interviewer asks to design an application from end to end. So if you have some practice, then you can easily clear this type of rounds.

Application resume tips for other job seekers

Tip 1 : Always attached your Project links in your resume. As it seems your project is genuine and you are confident in showing your projects
Tip 2 : Don't add unnecessary things in your resume which are not related to the job, like your 10th class winning tournament certificate or managing a college society. These things didn't create any impact on your profile and takes an unnecessary space in your resume.
Tip 3 : Always make a 1-page resume. If you are making more than 1 page then it means you have added a lot of unnecessary information which are not related to the job profile.
Tip 4 : Always show your Project and Past experience on top, just after your basic info and education. Since these are the things which should be on top to showcast the skills.

Interview Preparation Tips

Professional and academic backgroundI completed Computer Science Engineering from Punjab Engineering College(Deemed To be University). Eligibility criteriaCandidate must be femaleAmazon interview preparation:Topics to prepare for the interview - Data Structures, Algorithms, Graphs, Dynamic Programming, OOPS, Operating System, Database Management, C++,Computer Networks.Time required to prepare for the interview - 3 monthsInterview preparation tips for other job seekers

Tip 1 : You must have a grip over Data Structures and algorithms. Your concepts must be crystal clear. Pick one coding platform and try to practice at least 7-10 coding questions everyday. I completed around 200+ questions on Leetcode, 200+ questions on Geek For Geeks and around 30-40 questions on InterviewBit. 
Tip 2 : After attempting any coding problem, analyze its time and space complexity. See, if you can further optimize your solution. You can always check the editorials and compare your solution with it.
Tip 3 : Apart from coding questions keep studying concepts of Operating Systems, databases and object oriented programming. You can always refer to Geeks For Geeks articles for it. Also, Coding Ninja's Data Structures and algorithms course in C++ helped me a lot in improving my OOPS concepts specifically.

Application resume tips for other job seekers

Tip 1 : You do not need to have a long list of projects on your resume. One good project with proper knowledge of it will do good. Similarly, do not list down several number of skills. Few skills but roper knowledge of them are enough.
Tip 2 : Do not fake anything on your resume. The interviewer gets to know about it by asking questions. If you aren't able to answer, it leaves a negative impact.
