Algorithms Interview Questions
Algorithms interview questions on recognising the underlying pattern and reasoning about correctness, not memorising solutions.

The short version
Why the Algorithms interview is hard
Algorithm interviews test pattern recognition and reasoning under observation. There are far fewer underlying patterns than there are problems, and interviewers can tell recall from reasoning almost immediately.
What to expect
The rounds you should rehearse
Pattern recognition
seeing that this is two pointers, or a heap, or dynamic programming.
Correctness reasoning
arguing why your approach works, not just that the examples pass.
Progressive optimisation
brute force first, then improving it deliberately.
Avoid these
The mistakes that quietly sink candidates
Pattern-matching to a memorised problem and answering a question that was not asked.
Optimising before you have anything correct to optimise.
Declaring a solution finished without walking an example or considering edge cases.
Reading the questions is not practicing them.
Run a live voice mock tuned to the Algorithms interview. It follows your answers, probes the gaps, and scores you like a senior interviewer would.
