They were welcoming, a team leader interviewed me. Told me about the project they were working, and why they need more people. Asked me questions about the projects I worked on, some math questions, and coding challenges. He told me the interview has multiple stages, but didn't hear them back.

1. Interview started with project. 2. Technical interview comes after the project. 3. HR interview conducted after technical interview. 4. 1 week after HR interview while i am waiting offer they told me the position is on hold so we can not continue. Unfortunately 3 months later positions are opened again but still they do not contact me neither they reply to my submission for work.
