They invited me for an interview beforehand. And I studied and researched for the interview for 1 month, but they postponed the interview a few times due to the intensity of work. Therefore, I had to adapt my other work to this. And I couldn't concentrate on other interview invitations. Finally, 1 day before the interview, they canceled the interview, saying that they would not hire anyone anymore. Therefore, I wasted my time and suffered moral damage. One of the most unprofessional and disrespectful companies I have ever seen.
