HireVue CodeVue: Format, Difficulty, and How to Prepare

CodeVue is HireVue's coding assessment: one or more programming problems solved in a browser editor, auto-graded against hidden test cases, usually paired with a short recorded explanation of your approach. Employers attach it to the on-demand screen for software, data, and IT roles, so a single invitation can carry behavioral video questions and a coding task in one sitting. Large banks and enterprise technology employers are the most common users.

The grading has two halves. The code half is objective: your solution runs against the employer's test cases and passes or fails each one, with partial credit on some configurations. The explanation half is scored the way any HireVue answer is, on the transcript of what you say (see how HireVue scoring works). Candidates who ace the code and mumble through the explanation leave points on the table.

• Language choice. A dropdown of supported languages (Python, Java, JavaScript, C++, C#, and others depending on the employer). Pick the one you write fastest in without looking things up.
• Problem count and time. Commonly one to three problems in a 30 to 90 minute window. The clock runs across the whole assessment, so budget per problem before you start.
• Test cases. A few visible examples plus hidden cases. Passing the visible ones is the floor; the hidden ones check edge cases (empty input, large input, negative numbers, duplicates).
• The editor. Basic syntax highlighting and a run button. No autocomplete of the kind your IDE gives you, and no external libraries beyond the standard library.
• The explanation prompt. After submitting, a video question along the lines of "Walk through your approach and its time complexity," with the usual prep timer and answer window.
• Integrity monitoring. Browser focus is tracked, as it is in the video portion. Pasting in large blocks of code from another window is visible.

For entry-level and early-career screens, CodeVue problems sit at the easy-to-medium end: string and array manipulation, hash maps, simple recursion, basic sorting and searching, and the occasional data-structure question. Senior screens step up to medium problems with an algorithmic twist. The bar is "can this person write working code under light time pressure and explain it," which is why clean, tested, readable solutions to easy problems beat half-finished clever ones.

1. Drill fundamentals in your chosen language. Two weeks of easy and medium problems on any practice site, with the discipline of writing the solution in a plain editor rather than a full IDE.
2. Practice reading the problem twice. Most failed hidden tests come from a constraint the candidate skimmed past, not from an algorithm they could not write.
3. Write your own edge cases before you run. Empty input, one element, the maximum size, negatives, duplicates. Add them to the visible examples and run all of them.
4. Rehearse the explanation out loud. Sixty to ninety seconds: what the problem asked, the approach, why it is correct, the time and space complexity, and one trade-off you considered. Record yourself and listen back; this is the half most engineers never practice.
5. Set up like the video portion. Wired connection, closed tabs, quiet room, and the technical checklist in the main HireVue guide.

Submit a working partial solution rather than nothing: a brute-force answer that passes the visible cases earns more than an elegant idea that does not compile. Then use the explanation video honestly. Say what your solution handles, what it does not, and how you would improve it with more time. Reviewers watching the shortlist read that as judgment, which is a competency they are scoring anyway.

The HireVue interview questions guide covers the behavioral questions that usually sit in the same invitation.
