I am fine that up to the ~3 interviews covering the different aspects (say HR person checking the general personality, IT guy for i.e. Linux sysadmin knowledge mini-test, the team manager).
In 2020 after the Covid started, I got into the endless spiral of I believe 6 interviews spaced over a month or so, then the long wait and getting shorter contract with same salary but different from the advert job title. With the back against the wall I took the job. Within 3 months or so (including a 1 month training) they re-posted a job advert for my position. I had to extract from them an info that my contract described as "with almost automatic extension" will not be extended ("we run out of funds").
I work off my posterior for months to get this.
I would say that's the worst person to do the personality check. Instead, engineers the hire would actually work with should probably do the personality check.
Often HR is either a bureaucrat with a non-technical degree, or an inexperienced young "internal recruiter" with a non-technical degree and a pleasant appearance meant to attract responses on LinkedIn. Neither of those are uniquely well suited to judging personalities. (Unless this is another case of, #wontfix, we want to screen out engineers who have personality characteristics that random 24 year old sociology students don't like.)
Exactly this! They are probably the most incompetent people included in the hiring process, and yet they will take part in the decision making with their ‘magic’ personality judgement and culture fit skills, always making the wrongest decision ever. I had candidates rejected by HR because they were too charming, too lively, too <insert random characteristic>, to find them later employed in way better companies and roles. Well done HR, now you have your culture and team fit, for a team and culture you are not even managing.
Ah and your professionalism stops as soon as you hire someone. The rest of candidates might be left without a response even in their 3rd reminder. I guess it’s tough to even setup the auto email notification in the ATS tool you are using.
In short: shit on input does not bide well
