Positives:
- Speaks excellent English
- Obviously very familiar with Visual Studio, used short cuts like autocompleting property definitions
- Seems very calm and worked immediately, very straightforwardly
- Created well-defined methods on `Board` to facilitate various functions like "reveal box" and "flag box"
- Able to talk through his work well, explaining as he went along
- Used a nested loop and `Math.Max` and `Math.Min` to reveal box around the revealed box
- A user-facing thoughtful thing: he cleared the console at the top of each input loop
- Used `StringBuilder` to render the board output, but decided against it later
- Used string interpolation (newish C# capability) to render mine box content
- Excellent output message to user to give clear instructions on commands to input
- Showed familiarity with debugging
- Abstracted the PrintGrid functionality to a method to be able to call it multiple times
- Considered the user not knowing the array was 0-based

Concerns:
- Didn't appear to come super prepared with the solution in mind
- I'm not 100% certain he read the specification in detail, but relied on his memory of how minesweeper worked
- Very minor: used different terms for the same thing `bombFound` but `MineBox`

Other comments:
- Created class for `MineBox` and `Board` 
- Used multi-dimensional array of `MineBox`es in `Board` 
- Used `Random` to set mines randomly around the board
- Used a while loop in Program until `bool gameEnded` was reached
- Used `Convert.ToInt32` instead of `int.Parse` to get coordinates from console input line
- Ran into issues looping and redisplaying the board

Questions to ask:
- What could you do to take your game logic and render it any way you wanted to (console, HTML, graphical...)
      - Could do a virtual method on `Board` to allow clients to override it to render the board
- Why did you choose to have Program.cs "own" the rendering of the board instead of Board?
- Could you have Board "own" the rendering without it knowing exactly what it's renderings (strings, icons, HTML elements, etc)?
- Explain your choice to use `Convert.Int32`?
- You loop over the entire board or parts of the board (nested loops) a couple of times.  How could you abstract that logic while still using it for different purposes?
      - Would have to iterate the board each time. When I explained 
- Could you abstract the Game logic to untie it from the rendering and board?
