That, along with some family health issues, has left me with little time to think about signals, even though I’d love to see something like that added to the platform (badly).

So, I used my experience in other areas and pivoted. I’m now a Chief Architect at an HR SaaS company. My job is pretty broad, so I rarely get to do hands-on web work anymore. These days, that’s mostly something I do for fun in my spare time.

Rob Eisenberg @eisenbergeffect.com · 06/08/2026

I really wanted to keep working on the web and addressing gaps like these in the platform. But after leaving Microsoft, I applied to more than 100 companies for web roles that met my comp needs and didn’t get a single callback (it really hurts me to say this out loud). What was I supposed to do?

Default Isn’t Design. Familiar feels true but often isn’t. I wrote about the psychology (System Justification) behind framework monoculture, the quiet costs it creates, and a standards-first path that still meets teams where they are. Reflex → Evidence → Contracts → Users.

Last night I timed a product page load taking close to 6 seconds. This was on a desktop computer on a fast connection. I did a few tests on my mobile phone as well. Several times, the home page was completely unresponsive. One of the pages, I counted out loud to 30 before the content was visible.

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

There's no excuse for a distinguished engineer to be completely unaware of major performance problems that any customer can see and also unreceptive to discussion. I have a feeling that if their leadership understood they were preventably losing millions of dollars...

030

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

And just to be crystal clear: The issue was not the tech stack or the perf problems. The issue was the lack of ownership, awareness, and receptiveness to solving big problems, particularly coming from the Distinguished Engineer and the Principal who interviewed me. Egregious.

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

I'm interested in building great things and helping others who are also interested in building great things. I'm not interested in average. I'm not interested in ok. Great.

There were lots of red flags, but fortunately at this point in my career, I don't need to settle for mediocrity, deal with status quo crap, or endure toxic, broken culture. I will tell you straight up if I think you are making a mistake (tactfully and politely).

130

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

This was my 3rd interview, and prior to this no one had explained what this team was doing, what their stack was, their architecture, etc. The 2nd interviewer was from a different team and didn't know. The 1st interviewer gave me a different description. (And no, this wasn't about Web Components.)

110

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

Eventually, I told them "Let's stop the interview, because unless you are open to me coming in and proposing changes around X, Y, and Z, then I don't think I'm a compatible candidate."

110

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

The interviewers "had not heard" of any performance problems, and did not seem open to my architectural criticisms or ideas on how to objectively improve the performance and scalability of their systems (based on my career experience working on similar solutions for multiple companies in the past).

110

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

I visited their customer facing e-commerce site on a fast internet connection with a fast machine, and it's a trainwreck (3s+ to load the home page). If the customer can see how slow your crap is, even on a high-end rig, then you have a problem! The evidence of the failure is there for all to see.

200

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

Well, I suppose it's no surprise at this point, but this group had picked the worst possible e2e architecture combination (100% perf/customer experience failure rate at every company I've seen it done at.)

100

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

And just because someone at a big company has a fancy title, doesn't mean they know what they are doing either. Often, especially if they have been at the company for a while, they are least able to think about the problem in a fresh way and find the best solution.

110

Rob Eisenberg @eisenbergeffect.com · 13/06/2025

I had an interview for a Distinguished Engineer role at a big company yesterday... It convinced me once again that most big companies don't know how to do quality, performance mature engineering.

I definitely have concerns that this might break various JS frameworks, and potentially a lot of bespoke solutions.

I wasn't aware of this. This seems like a major breaking change, if true.

Rob Eisenberg @eisenbergeffect.com · 28/02/2025

The problem isn't that AI is actually capable of replacing software engineers. It isn't. Not even close. The problem is that there are a bunch of ignorant, foolhardy people in leadership positions who *think* that AI can replace software engineers. This is causing real harm.

A new proposal for Scoped Custom Element registries has been put forward by Apple. 🎉 github.com/whatwg/html/... Key improvements include: * Enables any element, not just ShadowRoot, to have an associated registry. * Unifies element creation & cloning APIs across DOM scopes. * Integrates with DSD

https://github.com/WICG/webcomponents/blob/gh-pages/proposals/Scoped-Custom-Element-Registries.md is a good proposal, but it ties the functionality too much to shadow roots. This is Ryosuke and I's...
