Pal Group interview questions

I only met the prescreening for the job interview. When I applied for the job, I got an email from HR, and we set a time for an interview. And that's how it started. They are supposed to tell me about the next interview within one week, but it's been 1 month since they didn't tell me anything. I emailed them about the interview, and they said the manager is busy and they will let me know once the manager gives them any update.
