I received an email from a recruiter that he is interested in my resume and would like to arrange a call with one of their team. So I sent my availability for about one month (all 5 days in next four weeks). It was just an email conversation, and I don't have a chance to input my availabilities in their system(usually they sent a system link to update our time availability) After that, I didn't get any email back from the recruiter (about 10 days right now).

1. Is that for hiring manager interview or onsite interviews? (Usually for hiring manager interview, they ask only 5 days of availabilities and ask to input through their system)
2. Is that means, they are not going to arrange an interview with me?
3. Is that okay to contact the recruiter again or do I have to wait for another 5-7 days?

I just would like to make sure before contacting the recruiter again.

Thanks.
