Interview Preparation Tips
Tip 1 : If you are good with any programming Language(Java and C++ preferred but again its your choice) start with DSA directly. Learn the basic Arrays, Linked List, Stacks, Queues, Trees, Hashing, Graphs, Dynamic programming, Heaps, searching and sorting. (PS:-Courses and resources i will not mention as there are many materials available just choose the one you like and start preparing!!)
Tip 2 : Once you feel OK start practising problems try to solve by yourself, if not take hints, and at the end you can check solution if still unsolved.
Tip 3 : Try to connect with people on linkedin. Try to know the techstacks and try to get referrals. Keep on applying once feel ready 80% because you are never 100% ready for anything.
Tip 1 : Keep your resume updated with all the tech stacks you worked on, your projects, your latest experience.
Tip 2 : The resume need to be short and crisp. it takes only a min. For HR to read your resume. and align it with job requirement.
