Coverfox interview questions

The interview was good, the interviewer made me welcomed, overall talked about my experience and scenario based questions, along with one coding question(straight forward array question), question was from advent of code

One of the most unprofessional experiences I've had. The first interview was scheduled in the second week of April after multiple follow-ups. The second round was finally conducted in the second week of May. After clearing that, I was told there would be just one more round, which took place in the third week of May. Post that, I was asked to submit documents for onboarding and offer release, which I promptly did. However, four days later, I was informed that the position was on hold. To make things worse, I noticed the same position being advertised again on platforms like Naukri and Indeed shortly after. It was a complete waste of time, energy, and trust. Extremely disappointing and unprofessional hiring process. Would not recommend engaging with them
