marques Q:
|
||
** DONE Give Feedback on Roopa
|
||
|
||
Roopas didn't seem like the strongest candidate to me.
|
||
|
||
During the short-form questions, she understood conceptually the JWT
|
||
and authentication vs authorization. She hasn't worked with K8s. With
|
||
a little guidance she did seem to understand what a container was. At
|
||
first the explanation was a "virtualenv".
|
||
|
||
My read on the answers were that the information she communicated was
|
||
decent surface level knowledge but when drilling down a bit further,
|
||
the understanding broke down quickly.
|
||
|
||
With respect to the long-form questions, she did much better. I liked
|
||
her answers for how she had improved the microservices in her previous
|
||
job. She had implemented a caching layer to keep data local within
|
||
their services as opposed to always hitting Salesforce. I would say
|
||
that her process for identitifying the issue was a bit lacking, but
|
||
she did provide results, so it worked out. The strategy to diagnose
|
||
the problem was more of seeing errors in logs and then looking at the
|
||
fix, but given that they didn't have much in terms of o11y, I think
|
||
that's the best she could have done.
|
||
|
||
She hadn't really known what we did, and wasn't able to make it very
|
||
far in guessing how provisioning would work. Given that she hasn't
|
||
worked in the space, I would expect her to think about what could
|
||
possibly go into this, but she didn't get far without Sarah leading
|
||
her through it.
|
||
|
||
Overall, I think that she's not fit for the senior position.

So the most called version of the =/organizations= endpoint is the one that’s called with the query params =?per_page=100=. Normally we're spending 200-300ms just getting the data to render the view.
|
||
|
||
At first I thought that includes and excludes would be the culprits here, but it doesn't seem so.
|
||
|
||
The view itself has many calls to `exlucdable_include_related` which is a construct that loads related values from the organization unless explicitly excluded.
|
||
|
||
This means that we're making several round trips to the DB to fetch data that is almost always in the view.
|
||
|
||
The best bang for our buck here is to parse the includes and excludes before we get to the view, and eager load as much as we can so that we save DB trips.

I raised concerns that this result is doesn't meet the bar to achieve success on the problem we set out to solve.
|
||
I also do believe it doesn't help solve the problem
|
||
|
||
When I express that the immediate response was defense. That's the wrong response itself.
|
||
|
||
I can be clearer -- There are two points I want here,
|
||
1. I don't think this solves the problem we were targeting.
|
||
2. We have finite time, deciding if we want to iterate or redesign based on learning is a decision to make.
|
||
3. Option 3 which I didn't think was possible is to completely ignore the point.
|
||
|
||
|
||
Here's what's worse though. We're trying to transform the team to be enablers for other teams, so we need to set the bar.
|
||
We have people on this team that are trying to raise / set the bar, and when they raise concerns they are dismissed without
|
||
consideration.
|
||
|
||
|
||
My main concern is our ability to field feedback on this team. I don't
|
||
think I have many occurrences of differing opinions being given the required space.
|
||
|
||
At best it leads to apathy, at worst it leads to mediocrity. Either way it leads to a dysfunctional team by design.
|
||
|
||
|
||
Those people trying to raise the bar aren't doing so selfishly.
|
||
We don't get immediate gain out of performing better or working harder, we still get paid the same.
|
||
So why would we be striving to raise the bar? This is a fundamental question to see if a leader understands
|
||
what high performers need to thrive.
