I applied almost half a year ago and immediately was notified that there were no spaces open. I was instructed to email the company every month to show my interest, and that they would keep my information on file. I took this to mean that they wouldn't contact me again, and so I pursued other employment options without contacting the company again. I received an email completely at random, long after I had applied, asking for my availability for a phone interview. I interviewed two days later and was offered the position six days after. My interviewer was very sweet and friendly. The entire phone interview took about fifteen minutes. Make sure you rehearse your answers to questions in advance and definitely ask at least one question at the end.
