The Danger Zone: Top Reasons Candidates Fail
Based on our database of Fresha interview outcomes, avoid these common traps:
- Failing to articulate the specific product decision and the reasoning behind it.
- Proposing overly complex ML models without considering simpler, effective heuristics first.
- Using pressure or authority instead of persuasion.
- Incorrectly implementing the sliding window or token bucket algorithm, leading to inaccurate rate limiting.
