Salesforce Senior Software Developer interview questions

I applied online for the position.I was contacted by the recruiter and gave a hackerrank.After that I had a phone interview with one of the engineers.Proceeding that I had a onsite with a mix of behavioral and technical questions.I was offered the position a week later.The recruiter was very prompt with dealing with the interview schedule and was also helpful with what kind of prep would be required to ace the interview.

The interview process is smooth and the coordinator is great. Everything else is terrible. First the interviewing team is purely consist of people from one specific south east Asian country, meaning they would highly unlikely to let anyone other than their own ethnical group pass. At least for two rounds of interviews, I presented totally correct optimal solution, and the interviewers didn't seem to know at all the optimal solution for the very questions they raised. The problems are not hard at all, if you are sharp engineer, you don't need to know the answers, once the interviewee wrote the solution on the white board, you should immediately grasp the "gist" of the implementation. In my case, rather than within 1-2 minutes to understand the code, I had to spend 15-25 minutes to walk on the example they gave multiple times, before they could understand the code. That's how competent the team members are. I just feel very funny that if you "grow" your team in this ethnic pure fashion, and allow anyone within your group to pass interview by asking 1+1, and fail anyone that doesn't belong, how can you build a dynamic creative team to solve hard problem. I will seriously think of declining any interview with any company that has purely one ethnic group in the interviewing team, their current ethic composition will clearly tell the interview result before it even happens. That's a total waste of my time. T
