So I'm talking about all the junior people (age 21-24) in my department who joined as the same time as me and I'm the only foreigner in the group. Language is not the issue I just feel that I get ignored by most of them all the time.
I'm not the loudest and most talkative person but I'm friendly and generally happy to socialise with and talk to anyone regardless of what they look like. I'm friendly with them but I just don't blend in in the group. Some people would not even look me in the eye. Some girls would even ask my number and to add me on Facebook at the end of the night and ignore me the next day. It's been 3 months and I've decided I'm not going to force myself to try and fit in.
Now I'm really worried that it will harm my career. I joined the firm not expecting (junior) people would get so cliquey and xenophobic. I planned to build a wide professional network and was going to try and be at least friendly with everyone. Now I found it impossible to build professional relationships with someone who would not even acknowledge my existence or respect me enough to even say good morning and smile after talking to me "friendly" the night before.
There are around 60 of us. I get along ok with I'd say 40 of them with 20 never paying any attention to me. I get along quite well with people from other departments. Most of those 20 people I'm referring to here are women.
I'm from Asia with a British father and I work in London. A lot of my friends prior to work are from all over the world.
