Advice being an interviewer

Advice being an interviewer

Feb. 18, 2018 10:00 AM mock interview as an interviewer on smallest substring containing unique keys

The peer worked very hard and also very open to advice, took the hint. The peer wrote the algorithm 
around 70 minutes including discussion, fixing all the bugs etc. 

I like to share that I could not finish the smallest substring algorithm in my first five practice 
on mock interview platform, in 30 minutes. I had different issues, but last 3 or 4 times I kept got
very good peer to help me, one is really good. Please take a look here, the peer helped me.

And the other one is also good, the peer helped me to pass all test cases in 30 minutes.

Just practice the same algorithm again and again, work on one thing a time.
