"The one standout is Triplebyte. Their graduates are 6 percentage points more likely to pass interviews —a serious boost, albeit not enough to dispel the negative signal that all the others carry."

I believe that interviewing.io and Triplebyte are associated entities. So grain of salt.

Berkson's paradox[1] is a useful lens to analyze inverse correlation. The pool of people doing interview prep are either smart or determined (to accumulate certifications) or both, but dumb and lazy people don't enter the pool, and an inverse correlation applies. Similarly, if an interview bar evaluates candidates though a combination of soft and hard skills and rejects those who lack both, even if soft and hard skills are independently distributed (or positively correlated with insufficient strength), soft and hard skills will appear to be inversely correlated.

Certs could be neutrally or even positively correlated with interview performance, but by pre-filtering the population, the opposite phenomenon arises.

What's important to understand is that certifications can be used in different ways by different industries.

Some use them as a minimum requirement for performing certain jobs. In such a case, listing certifications is valuable not because it says you are any good at your job, but because it shows simply that you meet the minimum requirements to be legally employed in your profession.

The other way they are used is as a marker of expertise. This is almost always misguided. Advertising one's certification status where none is required conveys a sense of insecurity, need for social approval, and overly strong attachment to formal procedures.

That does not mean you cannot learn something from a certification course - by all means! But true experts are always judged by their results, not by their certs.

Author/OP here. Just heard an interesting and relevant tidbit from someone who read the post. Apparently a while ago, Google fed resumes of employees into an ML model and correlated several metrics to the success of a specific engineer at Google. There was a lot of interesting data gathered from that but one that stood out was exactly that the number of certifications listed was inversely proportional to the engineer…

That is interesting data, but it's not that clear that you can derive actionable advice from it — particularly for employee candidates themselves. Is it the listing of certifications that is inversely correlated with the career progress of the employee? Or is it because listing a certification is strongly correlated to having one, with this being what is truly inversely correlated with career progress? And, if so, in…

One thing I've been thinking about is getting a GCP certification to increase GCP recruiter reachout down the road, as I've really enjoyed working with GCP and would like to stick with it in future work. Guess I'll just do more keyword work in the LinkedIn. :)

Exactly. I'm an independent consultant and I just got my AWS Pro cert for marketing reasons.

People with long About blurbs on their LinkedIn profiles tend to be weaker as well.

really? i found longer texts useful if they contain interesting details about the work of the person. shorter ones always leave me wondering who that person is.

To me, this alone could also be a collider/Berkson's paradox: Conditioning on making the cut, there is a negative correlation because you make the cut by either being extremely skillful or by having great certifications – one compensates the other. That in turn would mean that certifications are actually positively correlated with getting employed at Google.

You need the full picture, that is people not making the cut to exclude this pattern.

Really. I think this sums it up: https://devrant.com/rants/1807864/reality-vs-linkedin-profil...

Guys who spend a lot on self-promotion are tryhards. The really strong workers don't need to promote because their work history speaks for itself.
