Tips for Success at Persistent Systems
Start with the 9 most reported Persistent Systems questions, then work down the list.
Mediums are the bulk of the list (44%), so spend most of your time there.
Time yourself: 20 to 30 minutes per medium, then explain your solution out loud as if to an interviewer.
After each problem write down the pattern and the signal that revealed it. Patterns transfer to problems you have not seen.
Pair coding practice with a system design framework and prepared behavioral stories; most loops include more than coding.
