The short version
Both are desktop apps for Mac and Windows that help with the same interviews: coding, system design, behavioural, and role-specific rounds. The difference is the price. InterviewSoul costs $12 a month for 5 hours or $30 for 10 hours, and its free 30 minutes include every feature. Interview Coder is free to download, but its AI features need Monthly Pro at $299 a month or Lifetime Pro at $799 once. That makes InterviewSoul's Basic plan about a twenty-fifth of the price of Monthly Pro.

Before you use either
Many interviews, tests and employers forbid outside help, and some places require consent before a conversation is transcribed. Check the rules for your interview first. See our terms.
