MAQ Software interview questions

The process was simple. 30 minute phone interview talking about projects I've done and benefits the company offer. Then, they invited me for on site interview. There were two sessions; first session was with a PM, talking about my past projects, and the second session was with a UX designer in the team. I did some design exercise with the designer on whiteboard. Then I was given design exercise and after I submitted, they contacted me asking about start date. However, all of the sudden, they said that they would pause this process and resume in April, which I had no idea what this was about. They were not very clear if I have received offer or not.
