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.
