The descriptive were based on
1. Number Theory
2. Puzzle
3. Coding (Need not write compilable version but write a clear pseudo code).
4. Coding(Same as above).

Solve puzzles in heard on the street and day 1.0 book. Finish the course Data Structures and Algorithms.
Tips: Must correctly solve atleast 9 of the probability MCQ to ensure a final interview shortlist.
Duration: 1 hour 20 minutes
Total Questions: 14

Round: Technical Interview
Experience: He asks you write a pseudo code for the question asked. You must write a clear working algorithm. If you make small mistakes, he will try and correct you but huge algorithm errors can cost you the call for next round.Remember to give correct time complexities for the algorithm written. Be clear and try to explain your thinking process to the interviewer. If you are stuck, try to explain your idea and where you are stuck. He will help you move further. The whole interview lasted around 40-45 mins.
Tips: Maintaining communication with the interviewer is very important. Asked reason for low CGPA (mine was 7.94).

Round: Technical Interview
Experience: One o the question was - If you break a stick of unit length into two parts then what is the expected length of the longer part. A few others to calculate mean and standard deviations etc.
Tips: Must communicate with the interviewer and show him your arrival at the solution. They usually respond positively if you give them the correct answer. If you make a mistake, will give you a small hint to correct yourself but if you still make it, then you're out. If you are good with stochastic processes , then it would definitely increase your chances of progression.

Round: Technical Interview
Experience: Started with asking about favourite coding language. Chose Java , then asked basic questions like what is static class and what is it used for (OOPS concepts). Asked a few probability questions and then a few DSA questions.
Tips: Was bad in a section( I could not answer OOPS questions)but still gave me a chance again. If you recover from it and answer remaining correctly then you get to go to the HR round.

Round: HR Interview
Experience: Telephonic interview and was asked few questions about myself like education, Family background, Why job instead of higher studies, why job in finance and specifically Quantitative research, future plans etc.
Tips: This was not really tough. The HR also tried to explain what the job was about. They confirmed the Job Offer within 5 minutes after the phone call ended.
