Seeking Advice: Fresher MERN Developer Not Getting Interview Calls

Hi everyone 👋
I’m a fresher MERN Stack Developer (React, Node.js, Firebase, Tailwind CSS) actively applying to IT companies in Bangladesh, but I’m getting very few responses.
I’d really appreciate advice from experienced developers or recruiters on:
• Common mistakes freshers make while applying
• What recruiters actually look for in a fresher’s resume
• Portfolio project expectations for entry-level roles
• Best platforms or strategies for Bangladesh IT jobs
• How to properly approach HRs or tech leads
I’m eager to improve and learn from real industry experience.
