How to Prepare for a Product Management Interview

PM interviews are hard because they test a skill that's difficult to develop under time pressure: structured problem-solving. The process I used required months of deliberate practice before it clicked.

Study Materials

Books: Work through Cracking the PM Interview and Decode and Conquer multiple times. The thought process is very difficult to master on the first pass. Repetition is what converts unstructured thinking into the structured frameworks you'll need mid-interview.

Videos: ExponentTV on YouTube is the best practical resource. I solved two problems on weekdays and four on weekends. Eventually, I completed around 200 pages of practice problems. Record yourself talking through solutions — you'll catch where your thinking breaks down.

Reference: Manas's PM document requires 2-3 reads before it sinks in. thepminterview.com has additional resources. Learn a sample PRD format early so documentation questions don't catch you off guard.

Three Things That Actually Matter

1. Research your target companies and use their products. Generic answers don't work. Interviewers can tell when you've actually used the product.
2. Early failures are learning opportunities. After a failed interview, request feedback. Most companies will give it. Use it.
3. Consistency over cramming. 200 problems over three months beats 200 problems in one week.

The goal isn't to memorize frameworks. It's to internalize a way of thinking so the structure comes naturally under pressure. That takes longer than most people expect.
