You have a bad formatted resume. No one cares to read it. You don’t even think to change it. 2) You don’t have passion for testing. You just run behind software testing job as others do. You look for software testing job just for the sake of being somewhere employed. 3) You don’t see the job details before applying, whether it suits your profile or not. 4) You don’t have strong and VALID reason for the question – Why do you want to join/switch to software testing? 5) You have not spent time doing some homework on job openings – about the company, required skills, experience etc. 6) You are faking the software testing experience. 7) You pretend to have all the testing skills.
