Cohere Health Devops Engineer interview questions

In this whole process of 2 months, no one from this company's HR called me. When I tried to ask them to call me since I felt so disconnected with the whole process, they only wanted to communicate through emails. Took two months for the whole interview process with 5 rounds. The final round, the interviewer didn't show up. When I tried reaching out to my recruiter, they didn't lift my call and I kindly emailed them asking for an explanation. Two days later, I got a no-reply rejection email from HR. Thats the end of it after 2 months. I thought all my technical interviews went good!! I got good feedback in the interviews but very bad communication from HR overall. Please be respectful of your prospective employees' time and talk to them at least once to explain your interview process/timeline.
