I have to attend Skype interviews for new positions. However, I am still employed. Would it be best to work at home to be able to attend these interviews?
From home and on your own time. Take a half-day of vacation, or use your lunch break, or flextime. Just as you would if interviewing locally.
(@JoeStrazzere makes a very good point. Any company interviewing by Skype or similar should expect requests for after-hours calls, so there's no harm in asking. In fact, they should understand that your not wanting to do this on your current employer's timemeans you'd show them the same respect. And if they say no, that may tell you something about their corporate culture.)
- Have control and privacy over the space you are in. Coffee shops can have spotty wifi. You may be able to find a private room in your office but I would be leery especially if you are trying to be highly discreet. Home is best.
- Do not dishonestly take time away from work. If leaving your desk for a phone call, lunch, coffee with a friend or colleague, etc. is routine then you can leave your desk for this reason. However when it comes to a half-day interview you will definitely want to take a vacation day or otherwise take a personal day, not a sick day.
- Expect your interviewer to cooperate with you. If circumstances are really untenable, there's after-hours or you can knock it down to a phone, video-less interview.
You could choose a location near your work (a coffee shop) with Wifi access preferable in a quiet section. Always use your own equipment for the interview. Do a mockup Skype call from the location ahead of time to eliminate any access problems or noise related issues.
