    The process took 4 weeks. I interviewed at Salesforce (San Francisco, CA) in February 2015.

    Interview

    Several interviews. I believe one was behavioral while the other was simply the usual tech questions. Both were with managers. Since it was more for performance position, they asked how to optimize JavaScript code. They also asked basic algorithms using hashmaps and hashsets.

    Easy Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at Salesforce (San Francisco, CA) in February 2014.

    Interview

    The entire process was really straightforward. I had a phone call with an engineer where he asked me how I would design a hashtable without any built-in language tools. The second question was how I would optimize for either reads or writes and how I would approach load balancing during peak usage.

    Average Interview

    Application

    I applied online. The process took 4 weeks. I interviewed at Salesforce in February 2014.

    Interview

    I applied through the company website and soon after got an email from the Salesforce recruiter, asking me to schedule a call with her. This was a casual chat about my interests and past projects, along with some behavioral interview questions. Soon after, I had an interview with the Director of Performance Engineering and everything seemed to go just fine till then. I was then referred to a company performance engineer for a 3rd round. I thought I did well through the process, but never heard back from the recruiter. After weeks of trying to reach out, I was informed that the recruiter left and that they had cancelled all performance engineering internships. I lost so much time in the process.

    Application

    The process took 5 days. I interviewed at Salesforce (San Francisco, CA) in December 2011.

    Interview

    It was quick, 1 phone screen interview, after that onsite interviews(6 interviews onsite). Questions weren't too difficult but not very easy as well had to think, mostly related to performance in 3-tier architecture find areas that can be bottlenecks, some OO concepts, database indexing and sql queries. Overall the interview questions are position based, not very difficult although the test is tedious to finish but not impossible. With some Java programming practice one can clear the interviews.

    Interview Questions

    • Find performance bottleneck in 3 tier architecture   Answer Question
    • sql query to find count of students having same last name   2 Answers
    • database indexing, garbage collection techniques, difference between interface and abstract class, which one to use when, difference between hasmap and hashset and some more data structure related questions   Answer Question

    Negotiation

    Yes, I had an offer so was able to negotiate.
