Do recruiters require online assessments after candidates join an IIM?

Yes, many recruiters conduct online assessments (OAs) during campus placements at IIMs, even after you've cleared CAT and secured admission. Your CAT percentile gets you into the institute, but companies run their own screening rounds to filter candidates before interviews.

Which Sectors Use OAs Most?

Consulting and finance firms rely heavily on written tests. McKinsey, BCG, and Bain typically run case-screening exercises or problem-solving tests before inviting candidates to interview rounds. Investment banks like Goldman Sachs and J.P. Morgan often use aptitude tests covering quant, logical reasoning, and financial concepts. Tech companies including Microsoft, Google, and Amazon conduct coding assessments even for MBA roles in product management or business analytics.

FMCG and general management roles at firms like HUL, ITC, and P&G usually skip OAs and move straight to group discussions or interviews. The format depends entirely on the recruiter's hiring process, not the IIM's placement committee.

What Do These Tests Look Like?

Consulting OAs often feature case math, market sizing, and chart interpretation under time pressure. Finance tests include numerical reasoning, Excel-based modeling scenarios, and sometimes domain questions on valuation or accounting.

Tech assessments range from SQL queries and data interpretation to full coding problems in Python or Java, depending on the role.

From Reddit, we learnt that students at IIM Calcutta and IIM Ahmedabad often form study groups specifically for placement OAs, treating them as a separate prep cycle from academics. The difficulty varies, some firms set a low bar to filter only the unprepared, while others use it as a serious elimination round.

Timeline and Preparation

Most OAs happen during placement week itself, typically 24 to 48 hours before interview slots. Some firms share sample tests or prep materials in advance, others don't.

Students report juggling multiple OAs across different companies in the same week, so time management becomes critical.

You can compare colleges to see which campuses attract the most consulting or finance recruiters, since OA prevalence correlates with sector mix. If you're targeting roles heavy on assessments, budget time during Term 4 or 5 to brush up on quant, case frameworks, or coding basics depending on your sector.

Does Your IIM Profile Matter?

Not really. Once you're in the placement pool, recruiters evaluate you on the OA, resume, and interview performance.

X CAT percentile** or admission category doesn't carry forward into company assessments. Some students find this frustrating, others see it as a level playing field within the batch.
