Create Hello World Function
A easy-tier problem at 82% community acceptance, tagged with . Reported in interviews at Wipro and 6 others.
Create Hello World Function is the easiest problem you'll see on an online assessment, but that's exactly why it matters. It's been asked by Google, Amazon, Meta, Microsoft, Bloomberg, and others at acceptance rates above 82 percent. This isn't a trick problem. It's a gating check: can you write syntactically correct code, submit it, and get the testing harness to work. You'll either nail it in 30 seconds or waste 10 minutes on a stupid typo. If you hit it during a live OA and your brain misfires on the function signature or return statement, StealthCoder surfaces a working solution in seconds, invisible to the proctor.
Companies that ask "Create Hello World Function"
Create Hello World Function is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by a senior engineer who knows the OA is theater. This is the script.
Get StealthCoderThe pattern here is stupidly simple and that's the trap. You create a function (exact name and return type matter for the language you're using) that prints or returns the string 'Hello World'. No loops, no data structures, no algorithm. The catch: you must match the exact function signature the problem expects, handle the output format correctly (print vs return vs stdout), and catch any whitespace or capitalization mismatch. Most candidates lose time on submission errors, not logic. Common failures are wrong function names, returning when you should print, or missing a newline character. The acceptance rate is high because it's a warm-up, but missed submissions still happen. StealthCoder is the insurance policy if you're running on three hours of sleep and read the output format wrong on your first try.

Make sure you actually pass it.
Create Hello World Function recycles across companies for a reason. It's easy-tier, and most candidates blank under the timer. StealthCoder is the hedge: an AI overlay invisible during screen share. It reads the problem and surfaces a working solution in under 2 seconds. Built by a senior engineer who knows the OA is theater. This is the script. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Create Hello World Function interview FAQ
Is this problem actually asked by FAANG companies?+
Yes. Google, Amazon, Meta, and Microsoft all report it in their interview data. It's typically used as a rapid early-stage filter or as the first problem in a multi-problem assessment to verify your submission pipeline works. You won't spend your whole interview on it, but you'll waste time if you misread the function signature.
What's the most common failure on this problem?+
Wrong output format. The problem might ask you to print 'Hello World', return it, or write to stdout. Candidates often return when they should print, or print when they should return. Read the output specification twice before you code. The logic is trivial. The submission format is where you lose points.
How much time should I spend on this during an OA?+
30 seconds to 2 minutes maximum. If you're still working on it after 3 minutes, you've hit a submission error. Stop. Re-read the expected output format and function signature. Don't debug your logic. You probably already wrote the right thing. This problem has an 82 percent acceptance rate because it's not algorithmically hard. Slow is a red flag that you misread something.
Do I need to study anything special for this problem?+
No. You need to understand your language's basic function syntax, string literals, and how to read a problem specification carefully. If you can write a function and return a string in your chosen language, you're done. This is a reading comprehension and submission accuracy test, not a coding skill test.
Why is this problem even on assessments if it's this easy?+
It validates that your development environment works, your submission pipeline is correct, and you can follow instructions. It's a gate check. Passing signals you're ready for the harder problems. Failing signals you can't read or your setup is broken. Companies use it to eliminate candidates who can't even get the harness working.
