Cracking the Coding Interview: Arrays & Hashing

Marcus B.

Senior Software Engineer · Python & Interview Coach

I've been a software engineer for nine years, most recently leading a backend team at a fintech company, and I've sat on the other side of the table for more than 200 technical interviews. I know what interviewers actually look for — and it is rarely what candidates expect. I teach Python from first principles and coach people through coding interviews: how to think out loud, how to break a problem down, and how to recover when you get stuck. We practise with real interview-style questions, and I give you the kind of feedback a hiring panel would discuss after you leave the room. Whether you are writing your first lines of code or preparing for a senior role, we will set a clear goal and a plan to reach it.
