While many are still obsessing over LeetCode for their big tech interviews, most companies have already moved beyond simply testing your ability to code. Recently, one of our CSOAHELP clients faced what initially seemed like a fun little question in a Bloomberg interview—but it turned into a highly technical challenge filled with hidden traps.

Yes, the problem was based on Wordle.

The original question:

“Random 5 letter word. Guess the word in 6 tries or less.”

The system selects a random five-letter word, and the user has up to 6 attempts to guess it. After each guess, the system provides feedback:

• * indicates the letter is correct and in the correct position
• % means the letter exists in the word but is in the wrong position
• - means the letter does not appear in the word at all

Sounds simple? Many candidates might laugh at the idea—"Isn’t this just a guessing game?" Not so fast. From implementation logic to state management and edge case reasoning, this question tested far more than surface-level coding. Thanks to CSOAHELP’s real-time interview assistance, our client successfully navigated what turned out to be a deceptively difficult technical conversation.

On the day of the interview, the candidate joined Bloomberg’s remote session, and the interviewer casually said, “Let’s start with something light—implement a version of Wordle.”

It didn’t sound tough at first, but we knew these seemingly simple questions often lead to intense scrutiny. As the candidate opened their code editor, our CSOAHELP support team quietly connected via a second device and began monitoring the session.

After the candidate made the initial attempt, they were visibly nervous. Our support team immediately sent a guided text prompt: “You’ll need to maintain a hidden target word and return a feedback array for each guess. Carefully differentiate correct position vs. correct letter only. Avoid double-counting letters.” Alongside that, we sent a clean design suggestion outlining the data structure and algorithm flow. The candidate promptly repeated our guidance in their own words, and the interviewer nodded in approval.

As the implementation progressed, the interviewer interrupted: “Can you ensure your feedback algorithm handles duplicate letters correctly? Like in 'staff' versus 'fluff'?”

This stumps a lot of candidates. It touches on letter state flags, matching priority, and frequency counts.

We quickly recognized this as a classic follow-up trap and sent this through the support channel: “First process exact matches (*) and mark them. Then for %, count remaining letters and match only if unused. Prevent repeated matches.” The candidate delivered the explanation almost verbatim, in a calm and logical manner. The interviewer responded, “Great—that’s exactly the approach I was hoping to hear.”

But things escalated. The interviewer continued: “What if we want to support words of variable length, configurable guess attempts, and even non-English letters?”

This is where most candidates panic. Fortunately, our team had anticipated this system-level twist. As the candidate hesitated, we pushed another detailed prompt: “Avoid hardcoded word length. Make word size and attempt count configurable. Adapt logic to support Unicode input for broader language support.”

The candidate took a beat and then articulated this scalable design, even mentioning how Unicode sets can be leveraged for broader internationalization. The interviewer responded, impressed, “You’ve thought through this quite thoroughly.”

Later in the session, another advanced question landed: “If this game runs in a concurrent environment, with many users guessing different words, could shared state be a problem? How would you isolate and secure each game session?”

This shifted into systems design territory. We immediately prompted: “Use object-oriented design. Each user should have a separate game instance. Store state in session memory or user-specific context to avoid clashes.” The candidate echoed this back confidently and even added their own insight about exception handling. The interviewer’s demeanor visibly relaxed.

Across the 45-minute interview, the candidate faced 7 in-depth follow-ups covering algorithm edge cases, state safety, configuration, multilingual support, and system design. For someone who wasn’t fully prepared, this “easy” problem could’ve easily turned into a nightmare. But with CSOAHELP’s real-time assistance, our client was able to think clearly before each answer, speak with precision, and turn each potential pitfall into a chance to impress.

That’s what CSOAHELP does. We don’t just hand you code—we stand by you at the exact moment you need it most. We provide silent guidance through a second device, delivering technical direction, structured language prompts, and even code suggestions when needed, ensuring your mind stays sharp and your responses stay smooth.

Many great engineers don’t fail interviews because of lack of knowledge—but because pressure derails their clarity, logic, and communication. That’s why real-time assistance exists—not to cheat the system, but to support you when it counts the most.

Through this Bloomberg interview story, we hope more readers realize: interviews today test far more than code. What truly matters is how you structure your thoughts, respond under stress, and scale your solution design. And those are precisely the skills CSOAHELP is here to strengthen.

Are you ready for your next big tech interview? If you don’t want to choke when it matters most, if you want to navigate the conversation like you’ve done this a hundred times—CSOAHELP will be there, silently and effectively guiding you from behind the screen.
