13. How to Approach a Problem ForwardJS Hacking the Front End Interview
14. • Listen • Example • Brute Force • Optimize • Walk Through • Implement • Test Approaching a Problem ForwardJS Hacking the Front End Interview
15. Approaching a Problem: Listen ForwardJS Hacking the Front End Interview • Pay close attention to the problem • Ask questions to make sure you understand the problem • Pay attention to unique information
16. • Walk up to the whiteboard and draw an example • Make it specific: use real numbers or strings • Don’t worry about drawing edge cases Approaching a Problem: Draw an Example ForwardJS Hacking the Front End Interview
17. • Even if obvious to you, say it out loud. You don’t want the interviewer to think you’re struggling to see the easy solution • Explain the space and time complexity is for this solution Approaching a Problem: State a Brute Force Solution ForwardJS Hacking the Front End Interview
18. • BUD Optimization • Bottlenecks • Unnecessary work • Duplicate work Approaching a Problem: Optimize ForwardJS Hacking the Front End Interview
19. • Take a moment to make sure you understand the solution • This is a good place to do a bit of pseudocode but keep it super basic Approaching a Problem: Walk Through ForwardJS Hacking the Front End Interview
20. • Always start at the top left corner of the white board. You’ll need the space • Error checks: a good compromise is to write “Todo” just to show you’re thinking about errors. Approaching a Problem: Implement ForwardJS Hacking the Front End Interview
21. • Run through the code will small test cases • Run the code through edge cases • Think of this like a code review • Look for missing base bases in recursion • Integer division • etc. Approaching a Problem: Test ForwardJS Hacking the Front End Interview
