Interview Preparation Tips
Tip 1 : Try to learn DS+Algorithms from the basics in the starting phase of your preparation. Though, in the later stages of the preparation, some cramming can be employed for the problems generally asked in the interviews (but that too with proper understanding)
Tip 2 : Don't forget to prepare topics like OS and OOP. Although I was not asked much about these topics but my friends were asked some questions from these topics. These topics can be prepared in 2-3 days from YouTube itself.
Tip 3 : For an intern role interview, 2-3 projects including the college projects should be enough. You should be prepared to explain your project answer the basic questions like the approach which you followed, the problems you faced during the project, etc.
Tip 4 : If possible you can have a prior intern experience as well, but one thing for sure, preparing DS+Algorithms is much more important than this.
Tip 1 : Writing things which you don't know about properly won't give you much benefit. Rather, they can get you into problem if asked about them.
Tip 2 : Writing much about the things like extra curricular activities in the resume for software roles don't give you much benefit in my opinion. Though I wrote 2-3 PORs which had.
Tip 3 : Trying to make your resume longer unnecessarily won't give you any benefit.
