Wag! Backend Developer interview questions

The interview process was nice. Had a screen phone call with an HR person and went pretty well. An excellent discussion. Then in the next 2 days, I had an on-site chat with a person from the development team. We had a test and it went pretty well and got a good technical feedback on the spot. He said he'll let me know about the next steps and then after 1 week I haven't heard something not even a constructive feedback in case they didn't want to go further and that was very very disappointing.
