Why work with me?
- Hands-On ExperienceWith over 10 years in software engineering, including roles as a Lead Engineer at Meta and Mobile Tech Lead at Bloomberg, where I conducted hundreds of technical interviews, I know exactly what works.
- Real Success StoriesClients I’ve worked with have landed offers at Meta, Uber, Apple, Revolut, Monzo Bank, Nextdoor, and Adobe.
- Actionable FeedbackEvery session comes with detailed, practical feedback you can immediately apply to improve your interview performance and preparation strategy.
- Real Interview ProblemsYou’ll practice with the same style of system design, coding, and behavioral questions used at Big Tech companies.
- Personal ApproachNo generic advice. Just focused, 1-on-1 guidance designed to help mobile engineers succeed in their careers.
What I Can Help You With
- Mobile System Design (iOS & Android)Practice real mobile system design questions in a mock interview setting, just like top companies ask. I’ll guide you through your design, share tips, common patterns, and give you detailed, actionable feedback, including an honest assessment of your current level (E4, E5, etc.). You’ll know exactly where you stand and how to improve.
- Behavioral InterviewDo a realistic behavioral mock interview focused on big tech expectations. Topics such as project impact, conflict resolution, growth mindset, and effective communication will be covered. Then we’ll review your stories together, refine your answers, and I’ll give you detailed feedback.
- iOS Coding InterviewDo an iOS coding mock interview in common formats: Q&A, building a small app, or debugging code. We’ll go over key topics such as Swift, UIKit, SwiftUI, async programming, memory management, Core Data, unit testing, networking, and design patterns.
- Algorithm Coding InterviewPrepare for algorithm-focused coding interviews with realistic mock sessions with medium to hard LeetCode-style problems. I’ll provide detailed feedback, share practical tips, and give you an honest assessment of your current skill level to help you improve.
- Personal Interview PlanI’ll evaluate your coding, system design, and behavioral skills, review your CV or LinkedIn, and identify areas to improve. Then I’ll make a prioritized, realistic plan tailored to your experience level and target companies, with exact practice topics and a suggested timeline.
- Skill Assessment & DevelopmentWant to know exactly where you stand? Let’s review your skills, identify gaps, and create a realistic plan to level up your coding, system design, or interview skills.
How does it work?
Book a time
Pick a time slot that works for you from my calendar. You can choose a 60-minute or 90-minute session. For Staff Engineer and EM-level prep, I recommend 90 minutes for a deeper dive.
Set your goal
When booking, specify what you want to focus on. For example: “Mobile system design mock interview,” “Behavioral interview prep,” or “Meta full interview loop prep plan.”
Get the invite
Calendly will automatically send you a Google Meet link. Cancel or reschedule using the links in the invite. The 24-hour cancellation and rescheduling policy applies.
During the session
We’ll connect over video. For mobile system design, we’ll use Excalidraw for diagrams. Typically, there’s a short intro, then the mock interview, followed by detailed feedback, discussion, and time for questions.
