I was recently cold-called on Linkedin and decided to give it a shot, since it was with a relatively large internet company. I was flippant and didn't do a lot of preparation. The company was using Karat.io to perform tech screens. I totally flubbed the tech screen, I've done over 350 interviews at my current employer and I've seen lots of folks melt down, it was heinous.
Normally, I could care less, I got good data points for myself out of the interview and I had already decided I didn't want the job, that's not why I continued. However, after performing badly, it hit me that I have potentially cut myself off from not only this job but employment at any future customer of karat.io.
I reached out to Karat and they assured me data is only shared with the target company and for the specific position. The disheartening part is that there is no limit on the amount of time they keep the data. All it takes is poor company performance, coupled with desperation, and suddenly in the future they could offer a "pre-screen" service, where they screen candidates for you based on their past interview performance. I am at the behest of the scruples of all future executives of karat.io.
I have decided to refuse interviews with companies using a 3rd party screener on principle. I wonder, companies that are using these, why are you outsourcing potentially one of your most critical functions? If engineers do not conduct interviews, you will not build that expertise as an organization. Engineers at these companies, do you feel good with this practice?
That's why it's not a good idea to interview at a place when you're unprepared. Not only are you wasting both your and the company's time, but you're also hurting your chances of getting an interview call from them in the future.
I have seen a lot of people I know make this mistake -- not preparing enough for a interview, failing badly, and then applying to the same company 6/12/24 months later, and not even getting another interview. Very frustrating.
If interviews tend to be a little awkward to begin with, I find these online tech screeners to be over the top awkward. And with the results, we had a hard time determining how much value they added, because it was clear that the results were sub-par.
