I have a relatively easy one for you.

Create a website that gives the best possible word to enter into Wordle.

1) Download all the words in the Websters dictionary
2) If you can find a way to determine the most commonly used 5 letter word and order them.  that might be a plus.
2) Load all of the words that are 5 letters long into a database
3) create 26 extra fields in the database.  one for each letter. - run a script that populates each of those fields with the number of times each letter exists in the word
4) build a web front end where you can enter the word you tried and figure out a clever way for the user to enter the results (that Wordle responded).    Then narrow down the possible words that the user could enter.

i.e. yesterday, the final word was. whack.    We started by entering stern.  None of those letters were a hit.  I can't remember what we entered as our second word was,  but we had the k in the wrong position and the a in the correct position.  We luckily got whack on the third try.

Just see if you can get your front end to recommend a subsequent word based on the letters that have already been played and the answer that wordle provided.

I don't see it as a very difficult site ...  But on a job interview ... many folks have heard of Wordle so you've now got your foot in the door for common ground.   Then, the fact that you wrote a site to help - might show initiative.....

Just my 2 cents for the day.    

Congrats on the certification!!!!
