What I Can Help You With
  • Mobile System Design
    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 proven approaches, 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 Interview
    Do 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.
  • Customized Interview Prep
    Get a personalized preparation plan tailored to your goals, experience level, and target companies. Key topics will be covered, along with practical strategies to help you stand out and boost your chances of landing offers at top tech companies.
  • Algorithm Coding Interview
    Prepare 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.
  • CV Review
    Receive honest, detailed feedback on your CV or LinkedIn profile. I’ll help you highlight your most relevant skills and achievements so you get more interview invites.
  • Skill Assessment & Development
    Want 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. If you need to cancel or reschedule, just use the links in the invite—quick and easy.

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.
