Assalmualikum warhmathullahi warbarakathuhu
well Akhi i was a christain when i got me first ever job as an teacher in a primary school graduated to a secondry school it was quiet hard because you need to have good expectations i mean you need confidence && be mature before you can get a job, but Alhamdulillah am working in a Breavement Centre (Advicer) && subhnallah i got this job 3 half years ago love it, when i reverted i started to wear a Hijab (but i don't wear it at all times) but Alhadulillah am starting to wear it all times now, but anywho i don't think it's hard getting a job with a hijab nor a beard but you also need to think how the manager is like i mean were i work there are more christains but few muslims but Mashallah my Collegues allow me to wear hijab && also at salah time i am allowed to go in a peace room (as i can't pray due to my illness) i have to sit there on a chair facing the Qiblah with right intention, Alhamdulillah they are safe with that.
all i can say is you need to have confidence i mean soo many peeps whom have got a beard && wear hijabs are working am sure it's not hard, you just need to have confidence
do me a favour remember me in your Du3'ah, shukran
