Don't reveal too much personal information
To be frank, recruiters don't really care about how many brothers and sisters you have. So, don't start the interview with filler information. Revealing too many irrelevant details about yourself will make you come across as rather insightful about the job.
Interesting hobby's, certain personal interests or some fun facts might liven up the interview though. As long as they are relevant and give the recruiters insight to who you are as a person and a worker.
