Pgrammer

Pgrammer has a free Starter plan and a Premium plan at $12 a month, so you can try the practice questions before paying anything.

Pgrammer is an AI coding interview practice platform that generates coding challenge questions, gives hints while you work, and analyzes your solutions afterward.

You pick the difficulty level and choose from over 20 programming languages.

Both plans let you save your challenge history.

The Starter plan is described with unlimited real-time hints and unlimited solution analysis, while the Premium listing also includes hints and analysis, so check the plan page for the exact limits before you subscribe.

Hints are meant for getting unstuck mid-problem, and the analysis is where you review what you wrote.

It fits solo interview prep more than team use.
