This candidate passed the interview because of their ability to work through the problem. There may have been a few hiccups but nothing that would sink the interview.

Watch HERE and below review

What they did well

• Wrote out the input, output and example
• asked intelligent questions
• Thinking Greedy to start, challenges his own thinking and gets to the crux of the problem
• identified the greedy approach, and challenged his assumptions and showed that he couldn't prove it
• Feels like a conversation,
• Very good communicator
• Knew every individual coin was a base case
• Writes great psuedo code
• Great inspection, Good strategy, coding section
• Index selection optimization
• Caught his mistake and added 1 after being prodded

What could be better

• diagram isn’t clear how he is progressing through the problem
• started to fall apart when pushed on the runtime
• Realized the history of the coins didn’t matter after being prodded
• Got a little lost when he was strategized the coin change solution. Tied up in managing the index
• Didn’t know to reference the call stack when asked about top down vs bottom up
• Kept switching between top down and bottom up without bringing the interviewer along
• Psuedo code , didn’t really have time to code
• No need to do binary search on the coin, a premature optimzation
• First iteration of code wasn’t functional
• Had issues defining the output runtime never asked about the size of the coins
• Didn’t review his code too thoroughly
