The phone interview lasted 20 minutes, and the interviewer was not ready to interview me. Hasn't even looked at resume yet. They were too busy to interview. Then I was asked to download and use their apps and give feedbacks and some advices to improve their app.

Horrible interview process. Interviewers were disorganized, not-prepared and unmotivated. Would not want to end up, even if I had an offer. Interview is just a trailer, I don't even want to imagine how their company works inside.
