Rakuten Graduate Engineering Trainee GET interview questions

Interview was not hard per se, but they are extremely inconsiderate. They ghost you whenever they want and then reach out whenever they want after months. I got selected for an interview. I was not contacted for more than 2 months. No response from their end, so I was unhappy and it appeared very unprofessional because I was due for the interview. Then after 2 months they contacted me informally and asked if I wanted to give the interview. It was at such a short notice.
