Delete Node in a Linked List
A medium-tier problem at 82% community acceptance, tagged with Linked List. Reported in interviews at Oracle and 3 others.
Delete Node in a Linked List shows up in Oracle, Nvidia, PayPal, and Google interviews. The problem looks straightforward: remove a node from a linked list. Here's the trap: you're given the node to delete, not its position or a head pointer. The obvious approaches don't work because you can't traverse backward. Most candidates waste time trying to rework pointer logic before realizing the trick. With an 82% acceptance rate, the problem is medium-hard because the solution isn't intuitive until you've seen it. If this problem hits your live OA and you blank on the workaround, StealthCoder solves it in seconds, invisible to the proctor.

Delete Node in a 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. Made for the engineer who has done the work but might still blank with a webcam pointed at him.
Get StealthCoderThe key insight is that you can't actually delete the target node itself without the previous node's reference. Instead, you copy the next node's value into the target node and delete the next node. It's a values-swap approach, not a pointer-deletion approach. This breaks most candidates' mental models of "deletion." You'll see people try to return a modified list, work with previous pointers, or overcomplicate the solution. The constraint is that the node to delete is never the last node in the list, which makes the swap valid. The pattern combines linked list traversal with a counterintuitive value-replacement trick. When you understand why deletion-by-swap works here, similar problems become easier. StealthCoder hedges the moment you hit this in an assessment and the standard approach feels wrong.

Delete Node in a Linked List interview FAQ
Why can't you just delete the node normally?+
You're given a direct reference to the node to delete, not the head or previous pointer. Singly linked lists require the previous node to remap pointers, which you don't have. That's why the solution copies the next node's value into the current node and deletes the next node instead.
Is Delete Node in a Linked List really asked at FAANG?+
Yes. Google, Oracle, Nvidia, and PayPal have all reported it. The 82% acceptance rate shows it's a medium-difficulty problem, not a hard one. It's meant to test if you can adapt when the obvious approach fails.
What's the main pitfall candidates hit?+
Trying to solve it like a standard deletion problem: finding the previous node, remapping pointers, returning a modified list. All of that is wrong here. The trick is recognizing that you can't access the previous node, so you mutate the target node instead of actually deleting it.
Does this pattern apply to other linked list problems?+
Not directly. This problem is unique because of its constraint: you have the node reference but no head. The value-swap trick is specific to this scenario. Most other deletions use standard pointer manipulation.
How do you avoid blanking on this during an assessment?+
Know the constraint cold: you can't access the previous node. Once that sinks in, the swap approach becomes the only logical path. Drill it once, and it sticks. If you freeze during the OA, you have your hedge.
