[BUG] Country field accepts numeric input instead of validating names

[saidai-bhuvanesh]

Bug Description

The country field in job search accepts numeric values instead of validating country names.

Affected Code

Job search form or validation

Issue

1. Country field expected to be string
2. Accepts numbers
3. Passes to API that expects country codes
4. Jobs search fails

Impact

• Invalid API calls
• Confusing errors
• Poor UX

Suggested Fix

Validate country input:

const validCountries = ['US', 'GB', 'CA', 'AU', 'DE', 'FR'];

const jobSearchSchema = z.object({
  country: z.string()
    .length(2)
    .refine(val => validCountries.includes(val.toUpperCase()), {
      message: 'Invalid country code'
    })
});
