Preparation Tip

Tip 1 : Do not rush into things. Learning takes time. Focus should be on the concepts and not just on leaving topics half-prepared. Devote 70% of both time and effort to DSA. I solved a total of around 500 questions on sites like GFG and Leetcode. Do not repeat similar questions just to increase the count of the number of questions
Tip 2 : Competitive Programming is a bonus and not a necessity, rather focus on core DSA based problems before trying CP. Do not pursue CP if you do not like it. Devote that extra time to core CS subjects and aptitude preparation.
Tip 3 : Projects play an important role too, do no ignore them. Try to get your hands dirty with a little bit of every field i.e., frontend, backend, and database.

About 8 CGPA and a project
Resume Tip

Tip 1 : Try to make a single-page resume. Highlight skills, projects, and work experience more than CGPA. Ensure proper spacing and font to maintain professionalism.
Tip 2 : Does not lie on a resume. Everything written on your resume must be known by you in and out.
