Tips
- Do not panic. Build a solution involving the interview. Use Pen and Paper as much as you can.
- Ask for Help. I had asked for clues in both Rounds 1 and 2. Build the conversation.
- The interview process depends on the interviewer you get. Yet, the above statements are valid. The versatility is where the type of questions asked change a lot on this basis. Some get questions asked only on DSA, while some spend time on other CS Courses.
Remember, the goal is to showcase your problem-solving skills, adaptability, and willingness to learn.
