Final answer:
The full-time college student should search for job descriptions including keywords such as 'temporary', 'seasonal', 'holiday help', or 'short-term' that suggest the jobs are available for the holiday season and match the student's winter break availability.
Step-by-step explanation:
As a full-time college student looking to work only during the winter break for some extra money, it's important to search for specific keywords in job descriptions. They should look for terms such as 'temporary', 'seasonal', 'holiday help', or 'short-term'. These terms often indicate that a job is designed for a limited period, which aligns with the timeframe the student is available to work. Employers who are looking to fill positions specifically for the holiday season would likely welcome an application mentioning availability during the winter break.
It may also be beneficial if they mention any skills or experiences relevant to retail or customer service, as these industries typically have a surge in temporary job openings during the holidays. Setting up a weekly schedule for job searching and applying, as well as connecting with professional contacts, could provide extra efficiency to their job search efforts.
