Watch a Candidate pass a VR Mock Coding Interview

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

This is really impressive and of great value. The developers at iwanta.tech/ have an impressive background in VR application and software development, so they could handle tasks of any complexity.
