Salesforce Software Engineer - Security interview questions

They went very smoothly. I got the offer but they took it back in less than a day due to changes in the company rules and their new requirement of export license for international students. It was very disappointing.

I was contacted by a recruiter on Linkedin. After the initial call with her, I was asked to provide availability and another recruiter in Pittsburg took over. She explained that the first round would be a system design and when I said i have been preparing for system design, she came off unprofessionally and said we reject people who exhibit this kind of over confidence. I then gave my dates for the 1st tech screen. Even after giving the tech screen 4 weeks back, haven't received a feedback. I have sent atleast 4-5 emails asking for feedback. and next steps and have got standard reply saying "I will check with the team and get back to you by today". In total i spoke to 3 recruiter for 1 tech screen. Withdrew my application after the 4 week. The 1st recruiter was curious on why I withdraw my application and when I explained the reason she acknowledged that they have a problem internally. Complete waste of time.
