The first meeting was with the recruiter. Then I received a code challenge. After I submitted it, I didn't get any feedback. After 10 ten days I followed up but no response. 2 weeks, 3 weeks but no response. After more than one month they said ok let's move to the next step, I asked about the late response, they didn't have anything to say. Finally the last interview was done. The final interview was just about security, nothing else. I know security is one of the important categories, but not everything. Anyway again there was no feedback. Many times I followed up, again after one month their response was NO.
