Avocargo interview questions

I've interviewed with Avocargo 4 rounds, including one take-home case study (full power point presentation) which was discussed in-depth in a 1,5 hour interview afterwards. After 4 rounds of interviewing, in the last round, Avocargo said they will be in touch next week: I never heard back from the company. Very disrespectful hiring process as they take a lot of your time with several interviews, give you at home exercises that you prepare in a power point - but then do not have the courtesy to inform you on your application status. The interviewers were friendly, though.
