Summary

I went through a grueling 15‑hour on‑campus and on‑site interview process at Josh Technology Group for an SDE role, clearing multiple rounds but ultimately no candidates were selected.

Full Experience

I am sharing this because the industry needs a reality check on what "broken hiring" looks... (full original content omitted for brevity)

Interview Questions (6)

1.

Stack-Based String Reduction

Data Structures & Algorithms

Remove adjacent characters if they are consecutive (ab, ba) or circular (az, za). Removals must be cascading (if removing a pair might make the new neighbors consecutive, remove them too).

2.

House Robber III on Binary Tree

Data Structures & Algorithms

Maximum sum of nodes in a binary tree with the constraint that you cannot pick a parent and its direct child.

3.

Minimize Maximum Partition Sum

Data Structures & Algorithms

Split an array into M parts such that the maximum sum of any part is minimized.

4.

Custom BST Pruning with O(1) Space

Data Structures & Algorithms

Delete a node if node.val - inorderPredecessor < K. Must be done in one traversal, with O(1) extra space and no global variables.

5.

BST Pair Sum with O(1) Space

Data Structures & Algorithms

Find all pairs in a BST that sum to a target with O(1) extra space. You cannot use a stack or a temporary list; you have to implement a stackless iterator or use Morris Traversal logic.

6.

Generate M Numbers Summing to N (Backtracking)

Data Structures & Algorithms

Backtracking to generate all unique combinations of M numbers that sum to N.

Preparation Tips

I prepared by extensively solving LeetCode problems, focusing on arrays, trees, and linked lists, and practicing under time pressure.
