Apple maintains servicetalk[1] (java networking framework built on top of netty), so I'm guessing this is one potential JVM framework that was being used.
I think you've shared this on the wrong thread. There's a separate post every month for people looking for new roles. This month's post is: https://news.ycombinator.com/item?id=36573869
Are you talking about cash back? If so Amex does offer cards that support cash backs (I've had one for quite a few years). If you are talking about savings accounts, Amex also offers a High Yield Savings account whose rates are very competitive with other banks in the US.
Amex does have products that cover both these use-cases independently, so I'm assuming if Apple-Card indeed moves over to Amex these features won't go away and would instead be fulfilled via Amex savings account + Amex's existing cash back support.
`finally` will also cover scenarios where the an exception is raised from within catch, or if the catch block doesn't handle an exception that's raised in the `try` block.
I've definitely had bad experiences with take home tests, but well-run take home setups can be a lot nicer than phone-screens with live coding.
When I interviewed at my current employer they made it very clear that the take home was meant as a conversation starter, and everyone who gets a take-home made it to the on-site (virtual in this case since its a remote role). This removed the guess work into whether the test will be a waste of time, as there was a guaranteed on-site interview. The test itself was also a more accurate representation of a simpler version of problems that the team was working on, as opposed to a generic algorithm problem.
Overall this was the most positive interview loop I've ever bene through, and was a big factor in making a decision to say yes to the job offer.
I don't work for fly, but I'll say that while the end-user of fly.io isn't expected to run an orchestration system, fly.io themselves runs an orchestration system (nomad from what I can tell), so it seems like a fairly reasonable idea for a take home evaluation for an infrastructure role at the company to evaluate skills/knowledge about orchestration systems.
They posted maybe 6 months ago that they were migrating from Nomad to K8s (and expected it to take a while) so it's possible they're not on Nomad anymore.
