SAP Data Scientist interview questions

Very Unprofessional, I solved all hackerrank problem perfect. They are having trouble with scheduling first phone call interview. I have never seen any company do not know how to schedule interview for one month. Keep saying "We are coordinating scheduling your phone interview"

Following an HR Call, did a live coding interview for one hour through the Skype coding platform. After going over background, a simple coding question was asked, followed by one design question. Interview was fairly basic. After one week, HR called with offer.
