Megamind Consultants interview questions

It took a day got selected they sent a confirmation mail the next day I provided with the document they didn’t respond for 4 days after which I receive a call after many messages saying dont worry it’s just that they were creating a new team I asked them how much time it would take they said around a week well it took 20 days when I received a call from the manager saying that it was on hold and they might resume hiring again but I should keep looking for the job they wasted almost 1 month of my time very unprofessional
