Browse real LeetCode problems by category — arrays, trees, graphs, DP. Tell us your weak spots or let us recommend.
We match you with a senior engineer from FAANG whose specialty aligns with your chosen problem type. Pick a time that works.
60 minutes. Shared editor. Live video. Your mentor watches you think, guides you through sticking points, and explains the 'why' not just the answer.
Studies show pair programming transfers knowledge 2.5x faster than solo practice. When a senior narrates their thought process, your brain absorbs pattern recognition you'd take months to build alone.
— Williams & Kessler, 2002Most candidates fail not from lack of knowledge, but wrong approach — not verbalizing, over-engineering, missing edge cases. Live feedback fixes these habits in hours, not months.
— Tandom internal data, n=531On your own, a blocking insight can cost days. With a FAANG engineer watching live, the average time from 'I'm stuck' to 'I see it now' is under 8 minutes.

I'd been grinding LeetCode alone for 4 months with zero progress. One session with Priya and I understood DP in a way no YouTube video ever explained. Got the Stripe offer 3 weeks later.
The real-time feedback is what makes Tandom different. My mentor caught a subtle off-by-one error that would've tanked my Google interview. I passed the loop on my first attempt.
Worth every dollar. Marcus didn't just solve the problem — he taught me how to think through it. That mental framework is what I use in every interview now.
Every session is 1-on-1 with an active FAANG engineer — not a TA, not pre-recorded content. They interview at their company. They know the exact bar you need to clear.
No. You pay per session — one $49 booking at a time. No subscriptions, no long-term commitment. Try one session and decide.
After your first session, you can request a different mentor for free. We match you based on your assessment, but if the fit isn't right, we'll fix it.
Yes. Our assessment matches you with a mentor whose specialty fits your current level. Beginners are matched with mentors who specialize in foundational patterns.
Sessions are 60-minute video calls with live coding in a shared editor. Your mentor reviews your approach, explains the gap, and drills the pattern until it clicks.
