Wipro coding interview
questions, leaked.
25 problems reported across recent Wipro interviews. Top patterns: array, math, hash table. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Wipro's assessment is 56% easy problems, but that's a trap. You're looking at 25 questions that drill array, math, and hash-table patterns relentlessly. Two Sum, Remove Duplicates, Valid Anagram, Palindrome Number, Valid Parentheses, these are the gatekeepers. One hard problem (Median of Two Sorted Arrays) sits in the mix to break focus. Most candidates know the patterns but panic mid-implementation. That's where StealthCoder runs invisible during the assessment, surfacing working code the moment you hit a wall, letting you move to the next problem without losing momentum.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Wipro OA. The proctor cannot see it. Screen share cannot detect it. 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.

The topic distribution screams foundational mastery over algorithmic depth. Arrays appear in 10 problems, math in 8, hash-tables and strings in 7 each. You're not being tested on graph theory or advanced DP. Instead, Wipro wants to see if you can handle Two Sum variants, array manipulation (sorting, two-pointers, rotation), and string/hash-table lookups cleanly. The easy skew means speed and correctness matter more than creativity. If you blank on a sliding-window approach for Longest Substring Without Repeating Characters or fumble the enumeration logic in Count Primes during the live assessment, StealthCoder solves it in seconds without the proctor seeing a thing. Drill the top 5 problems hard; use StealthCoder as your hedge for the rest.

Wipro interview FAQ
How many array problems should I solve before the Wipro assessment?+
Focus on the top 5: Two Sum, Remove Duplicates, Rotate Array, Median of Two Sorted Arrays, and Kth Largest Element. Arrays show up in 10 of 25 problems. Master those patterns, then scan the remaining 5 array-adjacent problems for gaps. Two days of solid drilling on these covers 40% of the assessment.
Should I study dynamic programming before this assessment?+
No. Only 2 of 25 problems touch DP (Climbing Stairs is the visible one), and both are easy. Spend that time on math and hash-tables instead, which appear in 8 and 7 problems respectively. DP won't move the needle here.
Is the one hard problem worth studying for?+
Median of Two Sorted Arrays requires binary search and divide-and-conquer. Study it once, understand the approach, then move on. Most assessments let you skip or partially solve hard problems. The 14 easy questions are your score. Don't sacrifice breadth for one hard problem.
What's the fastest way to prep hash-table problems for Wipro?+
Hit Two Sum, Valid Anagram, and Longest Substring Without Repeating Characters. All three test the same core pattern: build a map, query it, slide or iterate. Hash-tables appear in 7 problems; these three account for the most common variants. A few hours nails it.
How important are string problems in this assessment?+
String appears in 7 problems, often paired with hash-tables or two-pointers. Valid Anagram, Valid Palindrome, Valid Parentheses, and Longest Substring Without Repeating Characters are the anchors. They're all medium or easy, so correctness and speed matter more than edge-case handling. Drill these first.
