Dear Dr Patel,
Last month I volunteered at your literacy programme, and now I am writing 1 (apply) for the Coordinator position. During my internship I learned a great deal and even managed 2 (raise) funds for new materials. I really enjoy 3 (work) with adult learners, and I would be delighted 4 (help) the team design weekend classes.
In my previous job, I avoided 5 (make) quick decisions without consulting the data, and I always tried 6 (communicate) clearly with stakeholders. I am keen on 7 (develop) partnerships with local libraries, and I would like 8 (arrange) a short call next week. If necessary, I am prepared 9 (relocate) to your city in July. I look forward to 10 (hear) from you.
Kind regards,
Monica Rivera
