Block by Block interview questions

I was called for a quick phone call, it was pretty simple. Process was quicker than expected from the time I applied. Then there was a group interview and from there I think a drug test was performed on a group others will come back another day if they are with block by block and not another recruiter

I applied for a position through Indeed and was scheduled for an in-person interview at their Boston office. The interview consisted of two interviewers who asked skill based position-related questions, and I was told I would hear back regarding next steps. I never received any response. The lack of communication after a formal in person interview was pretty disappointing and completely unprofessional.
