Mobileye coding interview
questions, leaked.
2 problems reported across recent Mobileye interviews. Top patterns: hash table, linked list, design. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Mobileye's assessment is built on a narrow, brutal foundation: hash tables and linked lists, full stop. You're getting two medium problems, both hitting the same patterns. Copy List with Random Pointer and LRU Cache aren't warm-ups. LRU Cache especially demands you thread a hash table and doubly-linked list together under real time pressure. You'll walk in knowing exactly what's coming. If you blank mid-assessment, StealthCoder runs invisibly and surfaces a working solution in seconds, no proctor visibility. Prepare for depth, not breadth.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Mobileye OA. The proctor cannot see it. Screen share cannot detect it. Built because the OA filter rejects engineers who'd pass the on-site. That's a broken filter. This is the workaround.

The data says Mobileye doesn't care about variety. Hash tables appear in both problems. Linked lists appear in both. The doubly-linked list requirement in LRU Cache isn't accidental. You're not solving ten different patterns. You're solving two problems that test whether you can combine data structures under stress and handle pointer manipulation without leaking references. LRU Cache is the real trial: you need O(1) get and put, which means the hash table keys to nodes, and the doubly-linked list maintains recency order. If you drill this one problem until it's muscle memory, you'll recognize its skeleton in Copy List with Random Pointer. That's your hedge. For the live assessment, if the implementation details slip, StealthCoder catches you and provides the exact approach to get unstuck.

Now make sure you pass Mobileye.
Memorizing every problem above in a week is a fantasy. StealthCoder is the hedge: an AI overlay that's invisible during screen share. It reads the problem on screen and surfaces a working solution in under 2 seconds. Built because the OA filter rejects engineers who'd pass the on-site. That's a broken filter. This is the workaround. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Mobileye interview FAQ
How much time should I spend on hash-table problems for Mobileye?+
All of it. Hash tables are in both reported problems. Spend three days on hash table fundamentals: collision handling, load factors, and how to use them as pointers to other data structures. You're not preparing for ten hash-table variants. You're preparing for two, and both use the table as a lookup mechanism for linked-list nodes.
Is LRU Cache really worth drilling before this interview?+
Yes. It's one of two problems reported, and it combines hash table, linked list, and doubly-linked list design in a single ask. If you can build LRU Cache from scratch without hints, you'll recognize the node-linking and order-tracking patterns in any follow-up they throw at you mid-interview.
Do I need to study design patterns separately for Mobileye?+
Not as a course. Design appears once in the data (in LRU Cache). Focus on understanding why you need a doubly-linked list for LRU Cache: you need O(1) removal from the middle. That's the design intuition. Skip abstract design theory.
What if I freeze on pointer manipulation during the assessment?+
You have a backup. StealthCoder runs invisibly during your assessment and surfaces working pointer logic in seconds, so you don't lose your train of thought mid-interview. Drill the patterns first. Use it as your hedge if things get stuck.
Should I prep for hard problems, or are mediums enough?+
Mediums only. The data shows zero hard problems reported. Spend zero time on hard variants. Master the two mediums at medium difficulty, then do one more pass on edge cases like empty lists or single-node graphs.
