answer:Regarding dress, I would say no. Even if it is a casual company, you want to dress better than the work standard. It is your first impression. You can relax later. If you know for a fact it is really casual, I would still go with nice slacks, a blouse and a jacket as the lowest level of dress, close-toed shoes and some kind of trouser socks or stockings. Thank-you notes. Everyone says write them and more than 90% of applicants don’t bother. I always noticed when an interviewee sent a thank-you note. It is really good for you in that it separates you from the herd, allows you to remind the interviewer who you are, and to make any extra points you thought of later. Do NOT ask your current supervisor for a reference unless they know and are OK with you job hunting. It could impact your current work environment. It will not hurt you with your prospective jobs. They will understand. Do you have a shortage of good references? If so, PM me and I’ll give you some ideas on other options than your current supervisor.
