Verkada coding interview
questions, leaked.
15 problems reported across recent Verkada interviews. Top patterns: array, string, binary search. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Verkada's interview is arrays and strings above all else. Eight of fifteen problems center on arrays, five on strings, and the rest scatter across binary search, hash tables, and design patterns. You're looking at four easy warm-ups, seven mediums that require solid pattern recognition, and four hards that combine multiple techniques in one problem. The mediums hurt most because they're the volume. If you blank on an interval-merging or snapshot-design problem mid-assessment, StealthCoder runs invisibly and surfaces a working solution so you move forward.

Array problems dominate your prep and they should. Expect interval work (overlapping, intersecting, scheduling), matrix operations, and snapshot-style designs that layer hash tables and binary search on top. Strings appear as calculation problems and filesystem parsing. Binary search isn't flashy here but it's glued to multiple mediums and hards, so don't skip it. Hash table design questions like LRU Cache and Time Based Key-Value Store show up frequently. The four hards combine sorting with dynamic programming or binary search with intervals, so the trick is recognizing which pattern applies. Most candidates drill easy problems and get wrecked by the mediums. If you haven't built the interval and design muscle before test day, StealthCoder is your safety net when a hybrid problem freezes you.

Verkada interview FAQ
How many array problems should I solve before my Verkada assessment?+
Eight of fifteen problems touch arrays, so treat this as your core. Drill interval merging, interval scheduling, and snapshot designs first. Target at least three solid passes through overlapping-interval and maximum-profit-scheduling variants. That covers half the problem set.
Do I need to master dynamic programming for Verkada?+
Two problems list it explicitly, but DP chains with intervals and scheduling in the harder questions. You don't need to be a DP wizard, but understand how to pair it with sorting or binary search. One medium-hard pass should suffice.
Is binary search actually important here?+
Yes. Three problems name it and it shows up in interval scheduling and time-based lookups. Binary search is a supporting skill that unlocks two to three hards. Don't neglect it even though it feels secondary.
What's the hardest topic to prepare for in one week?+
Design problems. LRU Cache and snapshot-array designs require building intuition about data structure combinations, not just pattern matching. If you haven't done design problems before, focus here first. Theory only gets you halfway.
Should I worry about the four easy problems?+
No. Matrix transpose and counting 1-bits are confidence points. Use them to warm up and save mental energy for the seven mediums. Your score lives and dies on the mediums, not the easy ones.
