For MCQ Round, we have 2 rounds:- 
1. Logical Reasoning (Window of 4 hours)
2. Mathematical Reasoning(Window of 4 hours)
The environment was fine. They gave an option of attempting a mock test in order to familiarize us with the environment

Logical Reasoning, in which there were 12 questions, and for each question we had a time limit of 75 seconds. There was a cut-off of 40 for the next round, and people who qualified were sent an e-mail with a link to continue with the process.

Numerical Reasoning, in my opinion, was the most challenging round. The questions were in a pair of 3 in which a table/bank statement was given and 3 questions were based on that. The questions were purely based on calculations and semi-subjective. The time given for the 1st question was 90 seconds and for the rest 2 questions, 75 seconds each

For Coding Round, 
120 minutes window(Test was of 90 minutes)
We have two questions
For the first question(30 Minutes)
For the second question(60 Minutes)
The tricky thing was we only had one attempt, i.e we were allowed to submit the solution only once.
