Reverse Linked List
A easy-tier problem at 79% community acceptance, tagged with Linked List, Recursion. Reported in interviews at Zenefits and 34 others.
Reverse Linked List is Easy, but 35 companies ask it and your acceptance rate on a live OA depends on whether you can code it clean under pressure. The trick isn't the algorithm, it's the pointer manipulation. Most candidates blank on the order of operations and end up with a cycle or null pointer. If you've drilled recursion and iterative reversal, you're fine. If you haven't, and it hits your assessment cold, StealthCoder surfaces a working solution in seconds, invisible to the proctor.
Companies that ask "Reverse Linked List"
Reverse Linked List is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by an engineer at a top-10 tech company who can solve these problems cold but didn't want to trust himself in a 90-minute screen share.
Get StealthCoderThe problem forces you to choose: iterative or recursive. Iterative is faster and safer in interviews. You maintain three pointers (prev, current, next) and flip the direction of each link as you traverse. The common trap is losing the reference to the rest of the list before you've reversed the current node. Recursion works but burns stack space and confuses the base case, many candidates recurse to the end, then panic on the way back. Both approaches live in Linked List and Recursion. The iterative path is cleaner for a live assessment. If you freeze on pointer logic mid-interview and can't visualize the swap, StealthCoder gives you the exact code to paste.

Reverse Linked List recycles across companies for a reason. It's easy-tier, and most candidates blank under the timer. StealthCoder is the hedge: an AI overlay invisible during screen share. It reads the problem and surfaces a working solution in under 2 seconds. Built by an engineer at a top-10 tech company who can solve these problems cold but didn't want to trust himself in a 90-minute screen share. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Reverse Linked List interview FAQ
Is Reverse Linked List actually asked at big tech companies?+
Yes. 35 companies report it, including Yelp, Snap, X, SAP, and Qualcomm. It's a classic screening problem. The 79% acceptance rate is high, but that counts practice submissions. Under live OA conditions with one shot and a proctor watching, the pressure changes everything.
What's the trick everyone misses?+
The order of pointer updates. Most candidates reverse the link first, then try to move to the next node, but they've already lost the reference. You must save the next pointer before flipping the current one. Write it down before coding if you're nervous.
Iterative or recursive for a live assessment?+
Iterative. It's O(1) space, clearer to trace, and faster to code under stress. Recursion is elegant but risky, the base case trips people up and it uses call-stack space. Save recursion for the follow-up if they ask.
How does Reverse Linked List relate to other Linked List problems?+
It's foundational. Once you own pointer manipulation, problems like Palindrome Linked List, Reorder List, and Swapping Nodes become simpler. It's a pattern anchor. If you can't reverse, those problems will confuse you.
If I freeze mid-interview on this, what do I do?+
Talk through the pointer logic out loud first. Draw it on the whiteboard or in the IDE. If you're truly stuck and the clock is ticking, StealthCoder runs invisibly and gives you a correct solution to unblock and move on.
