Meta interview notes, page 161 of 238

“I started with BFS because shortest path, but then fumbled a bit explaining why BFS guarantees it on an unweighted grid while DFS doesn't.” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“My first instinct was to jump straight into algorithms and collaborative filtering, which was probably the wrong move.” The rest of the author's notes on Product Manager interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I spent the first minute just picking a problem space instead of grounding it in user needs, which I think hurt me.” The rest of the author's notes on Product Manager interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The tricky part is that 'active' isn't just whether a follow_success ever happened.” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I jumped straight to BFS without really explaining why, which I think cost me points.” The rest of the author's notes on Machine Learning Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I went straight to engagement metrics and kind of forgot to set up what success even means for a feature like this before diving in.” The rest of the author's notes on Product Manager interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“Went with a min-heap of size k.” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“My first instinct was to use COUNT(*) which would've been wrong since the interactions column already stores a pre-counted value.” The rest of the author's notes on Data Scientist interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“Jumped straight into iterating the path and marking everything with '*', then realized mid-explanation I was about to overwrite the entrance and exit too.” The rest of the author's notes on Machine Learning Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The auto-disqualification of words with internal duplicate letters (like 'apple') is easy to miss if you jump straight to the subset logic.” The rest of the author's notes on Software Engineer interview at Meta, Onsite - Coding / Algorithms round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
