Crescendo Technology interview questions

Long first interview with HR. Straightforward test in R. Panel interview with IT and ML team. After 3 rounds of interviews I was told that in a few days I'll receive a case study but didn't hear back from them since then which I found to be a bit unprofessional. Here's the interview process: The initial interview was longer than other behavioral interviews. It took about 1 hour but moslty consisted of routine HR questions. R test on some basic R functionalities such as merging cleaning, transfering, etc. The technical team were professional and nice but they stroke me as a young and developing team. There are defenietly areas for them to improve.

Online assessment in R to be done over the period of a few days, a long phone call behavioral interview, followed by on site cultural and skills/knowledge interview, in which we went over my resume, technical acumen, and did some data science, statistics & probability based questions.
