I applied online. The process took 3 months. I interviewed at Invariant (Washington, DC) in Jun 2025

Question 1
What is one of the companies/clients you would be excited to work with?
Two interviews and a writing test. Never heard back despite following up. Weird because I was told it would take not too long only to be ghosted. Enjoyed the interviewer though.
