I am assistant. And my boss doesn't let me do other things apart from emails, organization of meetings etc. But I know how to help him to develop his business. How can I convince him to let me explain what I want to explain???

I went to one job interview for the position of boss' assistant and now they call me and tell that they want to hire me. But during the interview they asked me to prepare a coffee as a test. And now they tell me that the coffee was good haha like a joke. But for me it is not funny at all!! I know 2 languages and I find it kind of humiliating that they didn't pay attention to my knowledge. I don't know whether to accept this offer

The position of administration assistant is available in all employment sectors and is often regarded as a stepping stone to management or supervisory roles. Efficiency in general office duties is mandatory, but the work schedule will involve higher-grade computer and personal skills than those of an entry-level admin assistant as well as more time spent on a computer.
Required skills include proficiency in English, comprehensive computer skills and a professional outlook. The job’s administrative support element will depend on the company’s size and sector, and can be either general or specialised. Levels of responsibility vary, with combined responsibilities usual in the education, charity and health sectors
Required skills are easily developed, with many companies offering in-house apprenticeships in business and administration or encouraging promising employees to take vocational courses and degrees. Training by experienced colleagues is the norm, as is working alone and prioritising the workload
The salary offered to an administration assistant will depend on the size of the firm, the status of the job and the applicant’s qualifications and previous experience, as well as the company location. At present, the average is between £20,000 and £25,000.
