SmartThings Embedded Software Engineer interview questions

Phone interview with HR. Lasted 10 minutes. She asked me about salary expectations, experience with specific technologies and why do I want to work there. She assured me that I will get a follow-up either a text message either a phone call or an email if they decide to move forward or not. I told her that I'm actively interviewing and that I would appreciate a fast response from them. 1 month passed since then and sure enough no call, no email no message.
