5 Tips for MuleSoft Interview Preparation

Throughout my career I have interviewed for a variety of MuleSoft developer positions. Majority of those interviews were successful, but some were not. In this post I’m going to share 5 tips to help you prepare for MuleSoft interviews + 2 bonus tips for interview day tips.

Disclaimer: This post does not provide an interview question or certification exam dump. This post provides tips in which the reader can decide for him/herself the usefulness.

Let’s get started. Here are my 5 tips:

Tip #1: Learn the trend.

Prior to interviewing, look at common technologies needed for your role. Choose 1 or 2 technologies that you need to brush up on. For instance, while in the job search, I noticed that OAuth2 was mentioned a lot so I made sure to take a course on that subject. Kubernetes and Docker were also hot topics. However, don’t let the learning stop you from continuing the job search process.

Tip #2: Be Prepared.

Over the years, I found the best preparation for MuleSoft interviews was to mimic my preparation for a certification exam. In the past, I would go through the certification and interview process at the same time. Taking a look at course and exam datasheets to find concepts to brush up on. Consider reviewing the Mule 4 DIY exercises, practice quiz, DataWeave practice and your own practice projects. Review MuleSoft documentation to ensure you understand Mule 4, DataWeave, deployment and MUnit.

For architects, I would recommend you still cover the Mule development material but also look at the content covered in the Platform Architect and Integration Architect courses and certification exam. Also, reflect on personal experiences.

Tip #3: Reflect on past experiences.

Most jobs are looking for experience. Since that's the case, meditate on your past experiences. Think about the time you had to perform a data migration, integrate with Salesforce or design an API led solution. What challenges did you and your team face? How did you resolve it? What was the outcome?

If you have experience working with another integration platform or coding language, reflect on those experiences. If you have no experience, reflect on your training and practice work. For those that have no experience, I really recommend getting involved with the MuleSoft community and working towards contributing content or becoming a MuleSoft Meetup speaker.

Tip #4: Coding Challenges.

Put your best foot forward. Complete the challenges but make sure you show what you know. If there is a best practice, incorporate it into your code. For instance, although the coding challenge may say to implement an API. You may want to implement the API to accept HTTPS requests. Another example would be creating and encrypting sensitive properties in property files even if it is not mentioned in the challenge requirements. Lastly, create a README.md file. This is super important because it provides the interviewer with a description of the project, licensing information, installation and project execution details.

Tip # 5: Get Rest.

Rest or sleep is really important prior to your interview. Sleep helps your body to heal and rejuvenate. Get some sl
