I have been actively trying to fill spots for Sept the last month or so and while I've been getting an ok amount of calls, it's not resulting in many interviews. Actually I'm not even sure what a good response rate is lol. I have had only two interviews so far and they didn't result in a spot being filled. I'm starting to get nervous but will hope that I will have better luck soon. Reading threads like this is reassuring to me and keeps me positive.
Good luck to everyone.
