Mock Interview - LLD (Low Level System Design) with Madhav Oberoi

One machine coding problem, 50 minutes, same format as a real round. I'll give you the problem at the start, then you design it and write the code while I watch.

The feedback is mostly about the design. Whether the classes are in the right places, whether the patterns you reached for earned their place, what a reviewer would flag.

Book this if you have an LLD or machine coding round coming up. Tell me the company you're targeting and I'll pick something close to what they ask.

I also write about system design and CS fundamentals at askmaddyy.com, with interactive demos for most of it.
