Verkada interview notes, page 1 of 4

“The basic case is fine, loop through and compare.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“This was a lot more than just 'write some JS.' I started with a closure-based module pattern which felt right, but then got into the weeds on timer drift pretty fast.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“This one took me a second to size up.” The rest of the author's notes on Software Engineer interview at Verkada, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The naive approach is to just copy everything over and sort it, but they explicitly said O(1) space so that kills anything allocation-heavy.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The core of the problem is just a many-to-many relationship, which I spotted pretty fast.” The rest of the author's notes on Software Engineer interview at Verkada, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“Classic problem, so I'd seen it before, but the O(1) constraint is where people trip up if they haven't thought through the data structure combo.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I started with the ingestion to playback pipeline which felt right, but I spent too long on it and left myself almost no buffer for the deep dives.” The rest of the author's notes on Software Engineer interview at Verkada, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The graph traversal part wasn't too bad once I drew it out, but I kept second-guessing whether to go top-down from cameras or bottom-up from users.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The naive approach is just copy everything into a temp array and sort it, but they want O(1) space so that's out.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The problem looks straightforward until you slow down and realize the interval grouping is based on adjacency in the array, not on actual time continuity.” The rest of the author's notes on Software Engineer interview at Verkada, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
