> You want to hire experienced (or even senior) candidates and filter for domain knowledge? 1. Filter on experience & referrals. 2. Conversations: same approach as with the juniors, but much deeper and wider, relevant to your domain. 3. Call at least one reference to counter-check.
The reason I don't believe in (1) is that the candidate I described in my previous post claims nearly fifteen years of experience, some of it as a lead, and completely bombed our entire interview. Referrals are another matter (and they are indeed an excellent channel when you can get them), but they tend to be pretty low-volume - if you're hiring from the general public at all, presumably referrals didn't get you what you wanted.
By the same token, the majority of people we've placed so far were people whose resumes didn't particularly shine - but who turned out to be very good engineers when given an opportunity to actually work on a problem. (That isn't just my opinion, it's the opinions of the companies that hired them.)
For (2), I agree. We do do that as well (coding's one of three parts of our interview, not the whole thing).
For (3), have you ever had a reference give a negative review? A lot of companies make it outright policy to do so, and iirc there are legal restrictions on employers doing so in a lot of places. I wouldn't trust that with any reliability (although it's still good practice 'cause it's cheap).
> I've seen more rejected candidates because of "soft skills" failures than because of technical skills. And much more fired for behaviour than for technical/performance issues. Domain knowledge can be trained, fixed and integrated within the company. Behaviour cannot.
Of course soft-skills matter! I never meant to imply otherwise. But soft skills will only get you so far if you don't know how to do the fundamental responsibilities of your job.
