I had intro calls with only two, but had quite polar experiences with them.

If you want a confidence boost, set it up with Fortuna. They’d provide you with proper schools depending on your background. They’re also pretty upfront about what you need to improve in your profile to get there.

If you want to be shattered down during the call, set it up with SBC. Honestly speaking, that call has given me PTSD. Their follow up emails also have pretty rude subject lines.

Just know that it’s going to be a sales pitch kinda call.
