Drill the senior interview questions
Common Rails interview questions, four candidate answers each. The right pick names not just the fact but the trade-off — that's what interviewers score on. Wrong picks explain what each one signals to the interviewer.
Card 1
includes vs preload vs eager_load vs joins
Card 2
"Tell me about service objects."
Card 3
"How do you find and fix N+1?"
Card 4
"Sidekiq or Solid Queue?"
Card 5
"Turbo Frames vs Turbo Streams?"
Card 6
"Walk me through what belongs_to does."
