Data Innovations interview questions

Horrible. Was completely ghosted after 1st call with recruiter. Sent follow up emails weeks later to check on status, as he promised he would get back to me the following week and nothing, crickets. It isn't too much to ask for an email saying thank you but no thank you. Super unprofessional. Recruiter was late to meeting and I had to email him to ask why he hadn't called like he said he was. I should have taken that as a sign. Very disappointed and how I was treated.
