Leadership coaching
"Hi Mark, thank you so much for the coaching session – I genuinely appreciated our conversation. Your deep experience and calm, thoughtful approach created a space where I could reflect more clearly on how I present myself, especially as a leader. The way you helped me connect my experience to what hiring managers are really looking for made a big difference, and your insights on leadership – particularly around influence and impact – gave me a new lens to work with.

Mark's an exceptional coach—insightful, thoughtful, and brimming with ideas for tailored exercises and take-home practice that matched my needs. As a relatively senior engineering manager, I was looking for ways to demonstrate my leadership skills but also convey the degree of technical expertise I could bring to hard problems. Mark took the time to learn about my unique situation, asked tough questions to identify gaps that needed filling, and then dove into a series of practice interview questions that proved critical only a few weeks later.
Whether you're looking for career advice, hard-won industry insights, or just a few interview tips, Mark is a gem!

Interview coaching · System design mock interview
I wanted to practice with Mark after watching him do mock interviews on YouTube. I didn't quite know what to expect.
I got everything I could have expected and more. Mark is exceptionally professional. I felt that on the one hand I was getting the authentic experience of an interview that I wanted to practice, and on the other hand I was getting feedback at a higher level, with professional attention to the small details.
Mark was super nice, and flexible with my times and needs.
I practiced with Mark Mock System Design interviews and also a presentation of a personal technology project, two things I wanted to improve.
I felt I came away with relevant tips for both.
Highly recommended!
