As an eclipse fan, I may have experienced a teensy bit of schadenfreude while reading this.
He tells me, and I quote, "Oh, all the files are red."
Second wtf you may ask? In the goal of changing the storage of our data, he implemented 3 of ~10 behaviors of the existing library, and silently ignore all calls to the remaining 7. Guess which 3 were never used in the existing library!? :D
20 years "experience". Total incompetence. I should correct that: 17 years. After he was hired, during our first lunch together, he admitted he did nothing the last 3 of his previous employment, getting stuck in some org void where he just kept quiet and sat at his desk every day.
Yes, I'm on my way out.
A concrete example: one person could not get it through their head that they could write a function to return the correct value, then unit test that function with arbitrary known values. My question: "how do you know if it gets the right answer for 1,000,000,000,005?" What I wanted:
def fizzbuzz(n): ...
assert fizzbuzz(1_000_000_000_005) == "fizzbuzz"
"OK, we'll loop from 1 to n and write each of the values out. Then we can compare the contents of that file with a test case!"
"How is that going to work for values like 1 trillion something?"
"We can compress it!"
"And how long is this unit test going to take?"
"Well, let's assume we can process a million answers per second..."
"Aren't you going to run out of hard drive space at some point?"
"We can use `tail` to get the last few lines!"
"OK, let's start over. Can you imagine any way to test some arbitrary value in O(1) time?"
"Nope, can't be done."
"Sigh."
To help my explanation, I had a plot to show an example monotonic y=x^2 as a blue line and an example target value as a horizontal dotted red line.
One guy I had said something like, "You can start at the left of the image, then go down looking for a blue pixel. If the blue pixel is at the red line, you have found your value".
So, he wanted to search the image of the plot rather than the data behind the plot. I tried to get him to understand that was an example, and that we had the data, and that he would have to do the measurements himself, but it just resulted in a short interview.
I eventually told all the hiring managers that I could help interview again after their screening process was fixed, at which point I learned that they just removed software from the screening process to save time. This was a ~50% software position.
Same org as the dork above...
As more and more people delegate stupid things to their agent, this type of person will become increasingly common. Products like RustRover and CLion will be a much harder sell to audiences that don't even use an LSP in their day-to-day workflow.
JetBrains is probably working on a contingency plan as we speak.
