Gap Assistant Manager interview questions

Recruiter reached out through linkedin, did phone interview which went really well, she told me she will definitely be in-touch with me that following week and to be patient as she was busy with merchandising interviews but assured me I will get a second interview with DM, the following week i got no response so I emailed her and still no response then I see she is posting on Linkedin. Very unprofessional i was shocked what is happening with these companies and their unprofessional HR approach? Disappointing especially by gap whom is affiliated with old navy "top place to interview"
