IBM Associate System Engineer interview questions

I received a mail for the first round after 5 days of submitting my application. The whole process from my first round to last took almost 15 days. There will be 4 rounds in total. 1) Coding assessment (Scenario-based question - Using String manipulations). 2) Cognitive ability ( Having an idea of what games will be given would help to solve a lot faster) 3) English assessment ( each round will have 4 minutes of time slot. You can answer as many questions as you can in each round. The more you solve the better). 4) Last round is an interview. The interviewer was quite friendly and asked some basic questions from java, about my project and few personal details.
