Integrated Applicant Tracking & Interview Scheduling for recruitment agency

I'm in urgent need of an integrated Applicant Tracking System (ATS) and Interview Scheduling Software. As a recruiter, my primary requirements for this software are:
- **Resume Management:** The ability to track and manage resumes, CVs, and other applicant documents efficiently.
- **Interview Scheduling:** A feature that facilitates the scheduling of interviews, ideally with calendar integration to avoid conflicts.
- **Candidate Communication:** A system that allows for easy communication with candidates - be it to schedule interviews or provide status updates on their application.

The user interface should be:
- **Clean and Simple:** I need a system that is easy to navigate and won't be overwhelming for my team to use.

I need this project completed **ASAP**.

The ideal freelancer for this project should have:
- Experience in developing Applicant Tracking Systems or Interview Scheduling Software

Looking forward to hearing from capable and available professionals.
