The interview process at MuleSoft is a long and grueling one. I was referred by one of the managers there. I went through 4 rounds of interview before I was rejected. 1st Round - Interview with Recruiter 2nd Round - Interview with Hiring manager 3rd Round - Technical Interview 4th Round - Presentation and Demo (Face to Face) MuleSoft is hiring but the rate at which they reject their candidates is high. The percentage of rejection is 70%. 1st round is pretty straightforward. It is with the recruiter. She/He will walk you through the role and explain what the role is etc. Then they will ask you about your experience etc. They don't fail to make you realize how smart you need to be to work at MuleSoft. Apparently all the smart people of this planet are working here. 2nd round is with the hiring manager. Here the hiring manager will ask you about your recent projects (last 3 key projects). What problems did you solve? What difference did you make? Hint: Highlight your achivements. MuleSoft likes braggers. They like stories. Tell them a story. Apparently my answers were flat. That's the feedback I got. I also got a lecture on how smart people who work at MuleSoft are. Again!!! 3rd Round: Here comes the fun interview. Right from the start the interview focused on all the things I did not work on. I don't have a background with MuleSoft and APIs but I have a strong integration background. But the interview kept asking me specific questions about REST based APIs etc. I felt like I was being interviewed for things I don't know. I don't think he even looked at my resume. Kept asking me stuff which I have never worked on. If you think that my experience is not valid enough for the job then don't short list me. At this point I realized that I would not make it to the next round. But surprisingly I moved on the the next round. 4th Round: This is an interesting round. They will give you guidelines for an MuleSoft implmentation and a JVM troubleshooting exercise. This is given exactly 5 days before your face-face interview. There are two parts to this, 1) Troubleshoot a JAVA out of memory error: In this one they will give you a sample MuleSoft application which you import in on their AnyPoint Studio. Run the application. After a while this application will start throwing out of memory errors. You need to find the cause for this 2) Build an MuleSoft application using MuleSoft products. You need to have transformation, error handling etc. It should be a complete application. It should be innovative, you could use one of the MuleSoft connectors like Facebook, Twitter, Instagram etc. Just wow them. That's what they are looking for. You need to create a presentation and demo for this application. All in all you need to be smart as per MuleSoft standards. They don't care what experience you have with your previous employers. Just keep that in mind
