You want a platform, as a user I primarily want a tool, not a platform.

Maybe you got something useful to offer, but you need to demonstrate value first before hassling me with that.

In our job application frontend we don't even require logins or passwords. Only after you have finished your application and confirmed the privacy agreement we send an email with a confirmation link, only then you can add a password to follow the progress of the application, but even that is optional.
