IIM Shillong Interview Experience: GDPI Transcript with Questions from PI Round (March 27, 2026)

A detailed IIM Shillong GDPI experience from March 27, 2026, conducted at Peerless Hotel in Kolkata, gives us a useful window into what the selection process looks like this cycle. The candidate is an ECE graduate with 17 months of work experience at PwC India, and had already cleared interviews at IIM Bangalore, Lucknow, Mumbai, Udaipur, and Sambalpur before this one — so the account comes with solid comparative context.

The GD was built around a case study: a smart home device company selecting a chip manufacturer. It's a practical, business-grounded scenario that rewards both technical fluency and strategic thinking — a combination that fits well with IIM Shillong's profile preferences.

The PI panel had two male panelists — one in his 50s, one in his 30s — and their questioning styles were strikingly different from each other.

The first panelist went deep on technical fundamentals. Questions covered transistors, NPN and PNP transistor types, multiplexing, the differences between 3G, 4G, and 5G, and definitions of bandwidth. From there, he moved into work experience territory: client assessment methodologies at PwC, specific client names, organisational structure, and how the candidate had handled workplace conflict. There was also a mathematics component — continuous versus discontinuous functions — and the candidate was asked to draw and label an ellipse, which, by their own account, was a struggle.

The second panelist took a noticeably softer approach. He asked for five positive and five negative aspects of Kolkata, explored global warming causes, raised geopolitical topics involving the UN and World Bank, asked about the potential consequences of a nuclear attack, and invited reflection on an internship experience in Canada. The interview closed on a warm note — the panelists offered candies and water bottles as the session ended.

What's particularly worth noting here is the range. In our experience tracking IIM interview patterns, Shillong tends to combine genuine technical pressure with open-ended general awareness questions — and this account bears that out clearly. The two-panelist dynamic, where one tests depth and the other tests breadth, is a format we've seen surface consistently at IIM Shillong.

For candidates with an engineering-plus-consulting background similar to this one, the key takeaway is preparation across all three layers: your core technical domain, your professional work in specific and defensible detail, and current affairs that extend to geopolitics and environment. The ellipse question is a useful reminder that foundational academics are fair game, not just your recent work.

We also know from other candidates present at the same session that this experience was representative of the broader cohort's interview that day — which adds to its reliability as a reference point.

The overall picture is of a well-prepared candidate who navigated a genuinely demanding panel confidently. If you're heading into IIM Shillong interviews, this is the kind of range you should be ready for.
