I applied via Naukri.com and was interviewed before Dec 2023. There were 3 interview rounds.

Round 1 - Aptitude Test 

An aptitude test is used to determine an individual's abilities, assessing how they are likely to perform in an area in which they may have no prior training or knowledge

Round 2 - Coding Test 

Tests are typically programming challenges that help technical recruiters test programming skills and competencies of a developer or programmer. A good coding test will measure a candidate's capacity for problem-solving skills and understanding of coding.

Interview Preparation Tips

Round: Test
Experience: It included quantitative ability questions and a few subjective coding type questions. Nothing known about cutoff as almost major chunk of people appearing for the test were called for the interview.The criteria for test is mainly on CGs and at timesdepartments too.There are rare companies like BCG, DB who actually refer your resumes for interviews without tests.
Duration: 1 hour minute

Round: Technical Interview
Experience: 2 rounds of interview were there – first the technical interview which included questions on your resume. Detailed questionson every point you have mentioned, cross checking whether you really know aboutit at times asking you for examples. No speed math was included. The interview was purely on all the stuff mentioned in the resume.
Tips: Study the resume thorough with every point mentioned. Questionswere asked about things externally related (not in the resume) to stuffmentioned as part of skills. So while exaggerating any point be aware of everyfact about it.

Round: HR Interview
Experience: The HR interview included personal level questions like tell me about yourself, where you hail from, positives, negatives, why cognizant, why non-core, how do you see yourself after 2-3 years etc.The second stage may depend upon GDs or interviews. In this case it was purely one –on-one interview in both rounds.

Round: Case Study Interview
Experience: Mentioned about R a tool used in analytics and was talked about linear and logistic regression. Questions about Big Data Analysis and hadoop etc were asked.

General Tips: Its better to start from August solving CAT papers which helps a lot. Purefin certifications do help for companies like DB, Futures First, Nomura and all. Read only quantitative and a few previous years’ case studies (googled as per the company). Read one to two cases everyday and discussions related to them on the internet and write relevant points in some notebook at times searching for terms or phrases. Read the newspaper daily be it times or even the economic times – know whats happening in the world. They may ask you questions like – whats happening in the world. Be sure to answer them with what they would like to hear rather than what you would like to talk on.The situation is better for non core companies because majority of them don’t see the word department while recruiting from iit. Both for non-core or core: give your best for every round andeven if you don’t get selected for first round you can try to push your resumein on spot interview calls for companies you really want to be part of.Although it isn’t fair play but that’s what happens from Placemnt season day 2.And if the rest do it there's no point regretting than to be a part of it.
