Since you bought shares on 30 Oct, the shares will be credited to your Demat end of 1 Nov which is the record date. So you are eligible for the interim dividend. The RTA will credit the dividend directly to your bank account and this could take upto 2 weeks from record date.
1 Nov was record date and a day before 31 Oct was the ex-dividend date. You have to buy before ex-date to be eligible for the dividend.
