Questions people ask

How long do I need to prepare for a coding interview?

It depends on your baseline — PrepareAI builds plans from 1-week sprints to 3-month roadmaps, front-loading your weakest patterns first and tapering into full mock interviews as the date approaches.

Does it cover system design?

Yes. Plans include system design simulations (rate limiters, feeds, payment systems) with AI feedback, weighted by the seniority of the role you describe.

Can it adapt to my target company?

Yes — paste the job description or company engineering blog and the AI weaves their stack and interview style into your curriculum.
