Interview Preparation Tips

Professional and academic backgroundI applied for the job as Software Engineer in GurgaonEligibility criteriaNoGreyOrange interview preparation:Topics to prepare for the interview - Data Structures, Object-Oriented Programming, Algorithms, Dynamic programming, Graphs, Operating Systems and Database Management System,Java, MySQL, HTML, CSS, JavaScript, Nodejs, PythonTime required to prepare for the interview - 4 monthsInterview preparation tips for other job seekers

Tip 1 : Find a good course, and first clear all your fundamentals and implementation of every data structure. You should be thorough with their time as well as space complexities. 
Tip 2 : Upon clearing the fundamentals, select a platform where you have a large no of questions, also whose test cases are good. eg. LeetCode, InterviewBit or Codezen. Go and complete 300-400 questions.
Tip 3 : Also whenever you're not able to solve the problem, check out the editorial and then re-attempt it again. Also, check the discussion if there is some good solution to the same problem.
Tip 4 : For OOPS, DS and programming, I recommend Codezen, Leetcode, InterviewBit and GeeksforGeeks.
Tip 5 : For OS, DBMS and Computer Network, I recommend GateSmasher, Knowledge Gate and TutorialsPoint.

Application resume tips for other job seekers

Tip 1 : Resume should contain facts, numbers, and data comparison.
Tip 2 : Mention only those projects and internships in your resume that you are comfortable with, that is, you can explain to the interviewee.
Tip 3 : Technical achievements in the field you're applying to, would be good.
Tip 4 : DO NOT FAKE THINGS, the interviewer is smart enough.

I cleared all rounds with good feedback but after hr round, I called hr continuously for further process but I don’t know what happed they directly called me and said we put you on hold for 15 to 20 days. And i got one e-mail on next day that “we take this opportunity to thank you for showing your interest.” Because of this offer I left 3 more offers.
