Application story
I began my application journey by researching various companies known for their innovative use of Ruby on Rails. After identifying several potential employers, I applied to a mid-sized tech firm specializing in web development solutions, which I found through a job listing on LinkedIn. The application process involved submitting my resume and a cover letter detailing my experience and passion for RoR development. A few days after submitting my application, I received an email from the HR department inviting me to complete an initial coding assessment. The assessment aimed to evaluate my fundamental knowledge of Ruby on Rails and general programming skills. Upon successfully passing the assessment, I was scheduled for a phone interview with a senior developer. This call focused on discussing my previous projects, my problem-solving approach, and my familiarity with the RoR framework. Following the phone interview, I was invited to the company's office for an in-person interview. The in-person interview included technical discussions with team members and a meeting with the project manager to assess my fit within the team and company culture. Throughout the process, communication was prompt and professional. The HR team provided clear instructions and timely updates, making the entire experience smooth and well-organized. Overall, the application journey was positive, marked by well-structured steps that allowed me to showcase my skills and enthusiasm for the role.
