An interview is always amazing news. When you’ve applied for a job that you really want and they want to call you in for an interview, you will feel like you have achieved something already. However, when you see that the interview is at a time you cannot make and clashes with your conference call or meeting, your heart might sink.
Does it look like you aren’t committed to getting the job if you try to rearrange your interview? This isn’t the case at all, and you definitely shouldn’t think like this. If you are right for the role and the employer really sees something in you, then they will be more than happy to rearrange. Do bear in mind, though, that you will usually need to go for an interview during office hours, so you may need to book some holiday or rearrange some of your work around your job interview.
