I have 3 years of hardcore software development experience with India's largest retail company and 9 years of hardcore development and leadership experience with the world's 3rd largest retailer.

I applied for an SDE-III role opening at Walmart IDC Bangalore, which matched my domain and technical expertise.

I received an email within 2 hours stating that my resume did not match the job profile I applied for. I can't understand how this is possible.

It seems you need a recommendation from an existing employee of this company to even get an opportunity to appear for an interview. This suggests a degree of corruption within the Bengaluru Walmart IDC HR department.

Not given a chance to appear for an interview.
