You need a CTO.

You have a candidate, you’re not 100% sure, but you’re desperate.

Maybe you should take her? Move quick, get the person…

Don’t do it. 

The lazy option is to choose the wrong candidate.

The right option is to keep thinking until you find the right candidate. 

The candidate that doesn’t instil doubt.

That’s the only person who can do the job, there is no shortcut.

If you don’t have the answer, keep thinking.
