Meet the Mentor
Raja Naidu Kottana is a management professional and IIM Calcutta alumnus with a background in Mechanical Engineering from IIT Hyderabad. He has held senior leadership and P&L roles across organisations such as Aditya Birla Group, JSW, WayCool Foods, and Ascent Health, with experience spanning sales leadership, marketing execution, and business strategy. As a mentor, he works closely with candidates to strengthen how they structure problems, apply business logic, and communicate professional impact in interview settings. His mock interviews are designed to reflect real selection conversations, where thinking is tested, assumptions are examined, and responses are refined through detailed, experience-led guidance.
Mock interviews are most valuable not when they rehearse answers, but when they surface how a candidate is really being read. The difference between “knowing marketing” and “sounding like a marketer” often emerges only when responses are interrupted, challenged, and unpacked.
In a recent GoCrackIt mock interview, a marketing candidate from a premier B-school went through a full interview simulation—personal questions, strategy prompts, and a guesstimate. The discussion that followed exposed the exact signals interviewers look for, and the subtle gaps that often decide outcomes.
The Mock Interview
Personal introductions in MBA interviews
Marketing interviews almost always begin with personal questions. They are often treated as warm-ups. In reality, they are the first positioning test.
The session opened with a standard introduction.
Mentor: Hi. Can you introduce yourself?
Mentee: I am from Deoghar, Jharkhand. I completed my BBA in marketing and worked at TCS as a business process trainee. Currently, I am pursuing an MBA. I have done two internships in brand strategy and market research and have been a core member of the public policy cell.
The mentor moved away from credentials.
Mentor: What is one of the biggest decisions that you have taken in your life?
Mentee: The biggest decision was quitting my job at TCS after six months. Due to some personal issues at home, I had to resign. I decided to prepare for CAT and pursue an MBA, which I cleared on my first attempt.
Nothing in the answer was incorrect. It was clear, chronological, and honest. It was also safe.
In MBA interviews, these questions are not looking for background. They are listening for anchors—specific outcomes, moments of ownership, or decisions that signal how a candidate operates. When responses stay at the level of personal circumstance and timelines, the conversation often moves forward without a strong professional thread to build on, and the candidate loses the chance to shape where the interview goes next.
How marketing interviewers test business fundamentals
Marketing interviews often use simple concepts to test something more complex: whether a candidate can move from describing business outcomes to identifying the decisions that actually drive them. The mentor shifted the interview in that direction.
Mentor: If you are a manager and the CEO says you must increase the market share of a product, what are the things you can do?
Mentee: I can introduce the product into new geographies where it was not available earlier. And second, I will improve customer retention and focus on improving the repurchase rate.
The mentor stopped him.
Mentor: No. You are talking about outputs. To increase the repurchase rate, what will you do?
The mentee tried to recalibrate.
Mentee: I can add products or go for brand extension so that the average order value increases.
Mentor: What are the other two levers? Product, placement… yes.
Pricing entered next.
Mentee: I can play on pricing. For example, if I launch a product with premium pricing to attract customers.
The mentor corrected him immediately.
Mentor: Premium doesn’t always mean higher market share. Often it means the opposite. Increasing price does not logically increase share.
What was unfolding here is a common marketing-interview pattern. Candidates answer in results—market expansion, retention, repurchase—while interviewers keep pulling them back to decisions: what would you actually change. It was not enough to name actions. The mentor was also listening to how those actions were being classified. Pricing, product, and distribution were being mixed together. Outcomes were being treated as strategies.
In MBA marketing interviews, this is often where candidates begin to struggle. Recruiters are not testing whether someone knows what market share means. They are listening for whether business reality is being organised into controllable levers, and whether the candidate can speak in that language under pressure.
Why guesstimates appear in MBA interviews
After testing marketing fundamentals, the mentor shifted the interview away from domain knowledge.
Mentor: Can you give me an estimate of the number of chairs on your campus?
Mentee: Can I take 30 seconds to structure it?
He divided the campus into classrooms, hostel rooms, offices, and residential areas. He then worked through rough numbers for each category and calculated an approximate total.
What this part of the interview was testing was not arithmetic. It was whether the candidate could slow down, impose structure on an open-ended problem, and make his thinking visible.
Mentor: The structure is decent. But you need to make your assumptions clearer.
In MBA interviews, guesstimate questions are often used this way. They remove subject familiarity and observe how a candidate approaches uncertainty—how problems are bounded, how logic is communicated, and whether the interviewer can follow the reasoning from start to finish.
The feedback
Once the mock interview ended, the mentor shifted from interviewer to evaluator. He walked back through the conversation and named what it had revealed.
1. Marketing fundamentals and decision logic
The mentor began with the core of the session.
Mentor: Your marketing concepts are fine. Where you need to work is in making frameworks come out strongly. For any marketing question, first see if there is a standard framework. That will make your answer more comprehensive and to the point.
He tied this directly to the earlier exchange on market share.
Mentor: When you said “increase repurchase,” that’s an output. Improving distribution, changing pricing, working on product—those are inputs.
The gap was not familiarity with marketing concepts, but consistency in separating business results from the decisions that create them. He extended this into a preparation method.
Mentor: Take categories of companies and start applying frameworks deliberately. That will strengthen your concepts and also give you examples when questions are asked.
2. Personal introduction and professional anchoring
The mentor then returned to the very beginning of the interview.
Mentor: Your introduction is decent. But add a strong highlight. One point about what you did in your internship and what outcome it led to. Right now you say you did internships. Tell me what you achieved. Give one line as a teaser.
Here, the mentor reframed the personal pitch. The focus was about planting a concrete professional signal early enough to shape where the interview goes next.
3. Estimation, structure, and assumptions
From there, he moved back to the guesstimate.
Mentor: Your estimate is decent. The structure is fine. One major call-out is assumptions. See if you can make better assumptions, and always call them out.
This closed the loop on the estimation exercise. The candidate had broken the problem down logically. He was making assumptions, but he was not explicitly stating them as assumptions and the reasoning behind those assumptions, which limited what the interviewer could actually evaluate.
In marketing interviews, that distinction matters. Guesstimates are less about the final number and more about making thinking visible.
4. Interview presence
He ended on how answers are delivered.
Mentor: When you walk into the interview room, have a strong voice and a smile. It shows you’re prepared and ready.
This advice was framed as a signal. In high pressure interviews, how answers are carried often shapes how they are interpreted.
Conclusion
This mock interview illustrated how MBA marketing interviews are assessed in practice. The session surfaced gaps that are easy to miss while answering—confusing outcomes with decisions, leaving assumptions unstated, and opening interviews without a clear professional anchor.
These are interview-performance problems, and they usually become visible only when a conversation is guided, challenged, and unpacked by an experienced interviewer.
GoCrackIt mock interviews are built around that mentoring process—combining real interview simulation with structured guidance to help candidates refine how they think, respond, and present themselves in high-stakes MBA interviews.
