SAP Concur Project Manager interview questions

Got call from recruiter and did basic first interview. Had virtual interview with director who told me I seemed a great fit and definitely wanted me to do a second interview, they would let me know by the end of the week. After this got completely ghosted. Recruiter didn´t answer texts/emails, after calling finally got through and was told they still hadn´t made a decision a week later and would follow up the following Monday - again no response, tried calling a few times but seemed to screen calls. Basic decency would be nice, if I spend time doing an interview at least let me know if I am not proceeding and don´t say yes to then later not continue.
