Does my colleague likes me?

During the training week at my new workplace I got to know my new colleagues. However I got into another group so we won't work together directly. They treated me neutral but one of the boys was very kind to me. He was alwasy asking about my personal opinion on different things and asked about me. I had a feeling that he tries to get to close to me. At the end of the day he inveted me to party with him and his friends. What do you think is there any chance that he likes me?
