After 1 round of interview, they have given the practical test. After submission, i got the reply(after many follow up) that i have implemented the solution but not as per the senior DBA. After giving all the proofs that this is the only way to implement, again i got the feedback that your skillset is not matching the JD. Funny, how they have shortlisted my resume and processed 2 round of interview? they didn't screen my resume before with opening, or only they came to know about my skillset after 2nd round of interview.
