When I first started preparing for the interview, I was pre-occupied with ensuring I could solve problems within 20 minutes.

Algorithms

Agnosticism

  1. Find all possible combinations
  2. Select combinations that meet specified criteria
  3. Find optimal combination

Coding

Test every line

Don’t underestimate how tough this is

The 109 interview assessment is hard. This makes it all the more important to feel thoroughly prepared, knowing that you have well-practised skills and algorithms to fall back on when it is difficult to even remember your own name!
