CB4 Python Developer interview questions

Was contacted by recruiter and asked me to talk with hiring manager. After hiring manger they sent me take home coding challenge which I had to submit within time frame. Worked hard to finish it and submitted. Got another telephonic technical round where they asked me to write few SQLs and python code in shared doc. Nothing too simple or too complex. Intermediate level SQLs and Python code. After I am done he told me they will get back to me and nothing. It’s been 2 months I never heard from them anything. So unprofessional. They waste Candidates time and don’t have courtesy to send follow up email. How much time it take to send one email saying I am not selected or position is closed.
