How often should I test in a machine coding interview?
Continuously, not just at the end. Coding feature by feature without running the full flow means bugs surface at the end when you have no time. Test the full flow as you go, so issues surface while you can fix them.

More FAQs in Common Mistakes That Sink Candidates in Machine Coding Interviews
Trying to build everything. A broken superset loses to a working subset. Build the must-haves first and prove they work, then add nice-to-haves only if time allows. Interviewers prefer a working subset.
Because a working skeleton beats a beautiful unfinished app. Spending all the time on structure and styling with nothing working at the end is a common failure. Get something running early, then build on it.
No. Time is short, so write straightforward code. Do not build abstractions and folders like you are building a multi-year system. Over-engineering wastes time you should spend on a working result.
