ICON Data Scientist - Excel/SQL interview questions

The recruiter is not professional AT ALL and wasting my time. I was referred by an alumni and was contacted by the recruiter via text on Dec. 6th. We set up our 1st call on Dec. 8th but she stood me up without informed me. She texted me few days after and said she left for her PTO. We set up the 2nd call on Dec. 15th. I was ready to pick her call and she stoop me up AGAIN. This morning she texted me with an excuse of COVID test yesterday and would like to call me this afternoon. OK, I waited for her and she said she tried to call me but it went to voicemail straightly. I let my friends call me but no one has this situation. And I sent her message back, she didn't reply. I checked the career website of this position, it doesn't exist. I understand that the position might be filled but at least the recruiter told me the truth instead of making up lies to waste my time. Awful experience!
