Quick Answer
LeetCode is the default place to practise coding problems, with Premium listed at $39 a month or $299 a year. Good alternatives include AlgoExpert and NeetCode for curated explanations, InterviewBit for free practice, and Exponent Practice for live peer mocks. If English is not your first language, the gap is usually not solving but explaining: Mockly coaches you to talk through your solution clearly, from $50 a session.

Try the Mini AppThe Gap Most Alternatives Leave: Explaining Out Loud
In a coding interview, the interviewer scores more than whether your code passes. They also note whether you:
- Clarified the problem before starting. See how to clarify a coding problem in English.
- Explained your approach before writing code, and kept talking while you coded. See how to explain code out loud.
- Stated time and space complexity clearly. See Big O in English interviews.
- Stayed calm and talked through a bug. See live debugging in English.
A Weekly Routine That Covers Both
- Four days: solve problems on LeetCode or an alternative. After each one, explain it out loud for two minutes as if to an interviewer.
- One day: record yourself solving a new problem while narrating. Listen back for long silences and unclear phrases.
- Once a week before a loop: a live mock round with a person, either a peer on Exponent Practice or a Mockly coach who corrects your English.
