I applied to five different cashier and customer service positions about a month ago, but only one company acknowledged my application with a thank you, and then I never heard back from them. I'm feeling really frustrated because finding a job has been incredibly difficult for me. It seems unprofessional for companies not to respond at all, and I'm left wondering what this lack of communication means. I really need the money, and it's disheartening to put in effort and not receive any feedback.
