Hello HNI am an 16+ years of experienced software programmer, architect. I have the tendency to think I can learn anything if the job needs it within couple of weeks. I also see certifications generally take anywhere between 4-12 weeks based on the complexity. I am of thinking that what could you really master in 4-8 weeks than working on them day and day out and gaining experience. I usually have gained good records in terms of performance throughout my career. Are my thoughts valid about certifications or certifications are the way to go. I am searching for a Job but my Linkedin Applications are rejected and I am at loss to know the reason. I tick all the boxes for the jobs I apply. Whats wrong ?
