Maximize Score
Reported by candidates from Cvent's online assessment. Pattern, common pitfall, and the honest play if you blank under the timer.
Cvent's August OA threw a maximization problem at candidates, and the vagueness is intentional. You don't have the full problem text, which means you're going in blind unless you recognize the shape. These problems almost always boil down to either greedy choice at each step, dynamic programming to explore all paths, or a math insight that collapses the search space entirely. StealthCoder will read the actual constraints when you sit down, but going in with the frame "what am I actually maximizing, and what's my state?" will save you from panic.
Pattern and pitfall
Maximization problems at Cvent typically hide a DP or greedy pattern behind a business-sounding name. The trap is assuming greediness when you need DP, or vice versa. Without the exact problem, the safe play is this: if you can prove that a locally optimal choice always leads to a global optimum, go greedy and code fast. If the answer depends on what you've already chosen, you need DP with memoization. The common pitfall is undershooting complexity analysis and TLEing on naive recursion. StealthCoder will show you the exact input size and constraints in real time, so you can decide between memoization, bottom-up DP, or a closed-form math solution on the spot.
The honest play: practice the pattern, and have StealthCoder ready for the one you didn't see coming.
You can drill Maximize Score cold, or you can hedge it. StealthCoder runs invisibly during screen share and surfaces a working solution in under 2 seconds. The proctor sees the IDE. They don't see what's behind it. Built for the candidate who saw this exact problem leak two days before his OA and wondered if anyone had a play.

Maximize Score FAQ
Is this a greedy or DP problem?+
Without the full text, assume DP first. Greedy only works if each local choice provably leads to the global optimum. If you're unsure in the OA, start with memoized recursion. It's slower but correct, and you can optimize after proving it works.
What's the common gotcha in maximization problems?+
Forgetting that you must respect all constraints, not just the main objective. Re-read the problem for hidden limits on choices, ranges, or dependencies. Candidates often code a solution that maximizes in a vacuum and miss a constraint that breaks it.
How do I prepare in 48 hours if I don't have the full problem?+
Practice one DP maximization (coin change, house robber, longest increasing subsequence) and one greedy problem (activity selection, huffman). This trains your intuition for recognizing which pattern fits. Cvent OAs reward pattern recognition over novelty.
What if I blank on the algorithm during the OA?+
Write a brute-force recursive solution first, then add memoization. This is safer than guessing greedy and failing all test cases. A slow correct solution beats a fast wrong one, and you can iterate.
How do I know what to return?+
Read the output format carefully. Some OAs want the max value, some want the choices themselves, some want a count. Returning the wrong type or shape fails all tests silently. Verify on the sample before submitting.
