How long do Sri Lankan companies take to respond to internship applications?

I’m currently an undergrad applying for internships, mainly at larger companies and well-known organizations.

I’ve submitted around 14 internship applications over the past week, including roles in organizational development, business transformation, supply chain, business support, international sales, and similar areas. So far, I haven’t heard back from any of them 😭

For those who have applied for internships before:

• How long did it usually take for you to hear back after applying?
• Did companies contact you before or after the application deadline?
• How long should I wait before assuming I wasn't shortlisted?
• Is it normal to hear absolutely nothing for 2–3 weeks?

I’d especially appreciate experiences with larger companies in Sri Lanka (MAS, Hayleys, Hemas, EFL, Cinnamon), but experiences with any company would be helpful.

Just trying to get a realistic idea of what the usual timeline is because waiting without knowing whether applications are still being reviewed is a bit stressful 😅

Thanks!
