Before speaking to a single human, I was required to complete three separate assessments (TET, PI, and PET) totaling nearly 2 hours, including a proctored webcam test. The recruiter email didn't even wait for my response before another recruiter sending the test links, showing a sign of things to come, and chaotic.
I did the TET (the technical pass/fail test), then the recruiter sent me the remaining assessments. I completed all three assessments only to be rejected with no feedback, no explanation, and no human contact at any point in the process. The entire experience felt like being processed by a machine.
Advice to candidates: Know what you're signing up for. If you apply, be prepared to invest significant time before anyone at the company actually looks at you as a person. If the recruiting process is this impersonal, consider what that signals about the culture inside.
Advice to InterSystems: Candidates are evaluating you too. A little human communication goes a long way.
