Wellness Wednesday for April 16, 2025

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

We finally fired the guy. (I'm a SWE at FAANG.) I'm so relieved. You would not believe how much time and documentation it took. I'll estimate 20 pages of explaining his mistakes, not counting the code itself, over the course of six months. I have no idea how much time and energy our manager had to put into it - probably more than me. After 3.5 years, he was at what I consider 1-1.5 years of skill. How the hell he got promoted, I do not know.

I got asked to be his lead (kill me), which is good for my shot at promo to senior (results tomorrow!), so obviously I said yes. I immediately start complaining. Our manager doesn't see the problem. After a couple months of casual complaining (read: spending ~half my highly-valued weekly 1:1 sharing examples), I put together a meticulous spreadsheet. He sees the problem and says Junior needs to rapidly improve or will be fired. Junior makes no progress. Junior insists he is making great progress. Four months later, Junior is offered a severance or PIP and, in his first display of real intelligence, takes it.

Two of my favorite mistakes:

  1. He asserted that my code review idea to use an interface was conceptually impossible because when he tried it, the compiler said "attempting to assign weaker access privileges; was public," which apparently he found inscrutable. Solution: change the impl to also be public.
  2. On a project whose entire point was "set a timestamp, then filter stuff out if it's before that time," he set the timestamp wrong. It was set to the epoch. He had no tests that caught this. After this was pointed out, he pushed a new commit that was also wrong (differently). Twice. After four months on this project, he almost finished - the smaller half of it, which should have taken 2-3 weeks.

I have complained about this ongoingly to everyone I know for months. It was getting to be a problem. Work is so much chiller now. I can literally see the day he got fired in my sleep tracking metrics, as everything discontinuously improved.

What drove me the craziest was that my manager, reasonably, was too discrete to be straight with me about his agreement. I'm not sure at what point I really won him over. This left me chronically feeling unsure if, in the eyes of He Who Writes My Reviews, I was nitpicky and disagreeable, shitting on a coworker who he thought was just fine. Thankfully, the ending of the story strongly suggests he didn't think that, but it's still unclear if it hurt my reputation.

Or helped it - I did just save the company over 1 SWE-yr/yr, in perpetuity.

How did he get through the interview? Was it on-site, or could he have used AI?

It was virtual. I don't think he used AI. I think he got in during a low bar covid era. Leetcode is just easier than the job, in some ways. It's a test of "can you grind for a while with lots of money on the table." It doesn't show if you can sustain that, or if you have the attention to detail, or - in particular - the critical thinking to solve novel problems needed for the job.

As much as I could tell you a thousand stories of him being not up to snuff, he wasn't totally incompetent. I think he'll be adequate at a startup. Hell, he might even be OK if he started with us at new grad level today and just took ramping up more seriously. The bar isn't that high at FAANG, perhaps especially at mine, but it's not low, either.
