Orange interview questions

I got contacted by HR on mail and gave machine round of DS/Algo the same weekend. After more than a week I was called to give 2 F2F technical interviews. 1st one focused on Golang fundamentals and 2nd interview which was held shortly after focused more on web development with Go. Then again after 2 weeks I received a call from HR asking to give a telephonic Managerial round. Next day received a mail for f2f HR discussion. 7 working days after HR discussion I received my formal offer letter. As of interview questions, they were really good and discussed really professionally. But everytime I visited I had to wait for 30 mins.
