Working through a collaborative-editing system design with Varun was one of the most useful mock interviews I've done. They have a real talent for nudging rather than telling — asking exactly the right question at the right moment to push me toward a better design without ever handing over the answer. Their feedback on ordering guarantees and transport choices was sharp and practical, and their timing on when to interject was excellent. I came away with a clearer mental model and genuinely improved. Highly recommended.

I booked System design interview mock with Varun for Google L6 level and received solid rating from Google on Systems design and Architecture. I highly appreciate Varun for his solid approach and excellent feedback given during mock. I strongly recommend him.

I had the opportunity to take both behavioral and technical mock interviews with Varun on Topmate, and the experience was extremely valuable. Varun created a very realistic interview environment and asked thoughtful, relevant questions that closely mirror what companies actually look for. What stood out most was his structured feedback. After each session, he clearly highlighted my strengths, pointed out areas where I could improve, and suggested practical ways to refine my answers. His guidance on framing behavioral stories and structuring technical explanations was especially helpful. Varun is patient, insightful, and genuinely invested in helping candidates improve. If you’re preparing for interviews and want honest feedback along with actionable advice, I would highly recommend taking a mock interview session with him.
