Uber is a ship of Theseus. Lots of early people left since the Travis days. Since then, fixing the reputation damage has been a big focus in the company. Safety center, electric fleet commitments, DEI, Ukraine initiatives, etc, are all newe

Are you using this to build the product itself? Seems like a prime candidate for dogfood. If yes, where has it been useful, and if not, what does it not handle well?

I can't speak for every company, but the impression I get is that recruiters at the FAANGs of the world seem to search for various coarse rubrics that may or may not correlate with whatever they are looking for, be it a high number of

OAs aren't super widespread in "elite" companies for a variety of reasons. One is that sourcing recruiters are not equipped to handle technical screening logistics. They can't tell, for example, if a solution works but h

Many of us went through circuitous routes. My title is SWE at a big tech company and I interview SWE candidates, so I think I'm relatively close to how the sausage is made in terms of the pipeline through which most engineering candida

Then you joined big tech at the peak of the pandemic boom, when it was completely fair game to for recruiters to be poaching even foreigners due to the outsized growth outlooks. You should be aware that the economic environment has basicall

Yes. These days onsites have at least three categories of interviews: leetcode style, system design and behavioral. For L5 level (senior) and above, the latter two tend to weigh more heavily. It's also more common now to have two codin

The problem isn't demonstrating understanding of what a cache does conceptually, in fact any SWE worth their salt ought to be able to explain caching. The problem is if the candidate's decision to add a cache causes the system beh

The way it typically fall aparts for my candidates is I ask about optimizations, they say X could be cached, then I ask about cache invalidation and lo and behold, it didn't even occur to them that the cache needs to be invalidated at

I guess I'll echo some of the other comments re: extensibility. For us, Bazel's Starlark language is useful because it allows us to integrate w/ non-JS things like protobuf schema definition files. I suspect most companies ar

IMHO, if you're targeting the Javascript ecosystem, this area is already fairly crowded, with Turborepo, Nx and various open source tools providing various degrees of functionality (Bazel, Pants, Lerna, etc) already competing in the sp

Freelance is all about your network quality. When I did part time freelance to bootstrap my career I too got my dose of difficult clients. Then years later, I did a switch from FTE to consulting, with a single high quality client, and it wa

Earnings calls are post mortems for the performance of the previous quarter. A post mortem itself is just an analysis, it doesn't even have to be about a screw up. Screw ups are something else. When you think about cases like WeWork or

I'm seeing a lot of this "screw up = get fired" narrative lately and I think it's a bit ironic. Talk about screwing up in engineering contexts and suddenly the tune changes: now people will talk about improving processes

As someone with more than 15 years of experience and who has leveraged my open source work to improve my own career, my two cents is that GP has a fairly sober view on OSS as a job: Filippo is an outlier among outliers. Most people simply d

We use it extensively but are migrating away from it at Uber. Its strictness is a double edged sword, it often trips people up with checks that are pedantic but not fully sound. For example, TS will gladly accept that `if (typeof foo.bar ==

See the sibling comment from oblosys for an example where the exact same code can give different results in vanilla JS vs after a tsc pass. As you can see there, the problem is that an identifier can simultaneously represent a value and a t

I've heard reports that recruiters might spend all of 15 to 30 seconds per resume during a screening exercise. Never mind not having technical expertise to ask technical probing questions, sifting through the top of the funnel is mor

I've lived in three and find it amusing how there's two camps arguing with a straight face as if they could generalize anecdotes/conclusions about large amorphous entities. Both Norway and Venezuela are western countries. Tok

Not sure what `Promise.race(Promise.all(promises), loop());` is supposed to be doing. Promise.race only takes one arg, no? Also not sure what partialUpdate is supposed to be doing. Is that assuming some React-like diff reconciliation? Perso

No offense but this comment reeks of bias. For one thing, if by your own analysis, these companies' interviewing processes aren't effective, there's logically a conclusion that yours also aren't, given that interview pro

Upgrades come in a spectrum. Some are able to automerge via dependabot or similar tools, some need minor codemodding and can be managed by tools like soucegraph's new offering. Some take months of dedicated effort and digging through t

You use a build system. There are a number of open source ones, we use Bazel. In a nutshell, it keeps track of dependency graphs, so you can test only affected projects. It can also cache execution of unchanged transitive steps, so you can

It's the same convo as docker: can't one just use setup scripts for reproducible envs? In theory yes, but in practice, theory and practice aren't the same thing. It's easier to apply best practices to a greenfield projec

One of the reasons we developed devpods was because our setup scripts were unmanageable. Instructions to new employees would say things like "run this thing, scroll up past dozens of pages of stdout noise and manually deal w/ the

The joke is that we love them so much that we have many of them. In seriousness, we historically used microrepos and just getting to language-specific monorepos was already a monumental effort.
