    I have been working at Twilio full-time (Less than a year)


    I have now worked for 5 different companies and Twilio is by far the best. While most companies talk a big game about caring for their employees, Twilio actually means it and backs it up. Especially during COVID-19, Twilio has been going above and beyond to make sure that as employees, we feel included and valued. The career trajectory and culture alone make this an awesome culture to work for. Plus, the perks are pretty good too.


    In terms of working in sales, Twilio is definitely not a traditional sales company, which is probably both a pro and a con at times. If you are a salesperson and are looking for a traditional software sales company, then Twilio may not be the best fit. But if you are a salesperson that is highly adaptive and are seeking a supportive environment that pushes you to try new things, then you will do very well here.

    Advice to Management

    Keep doing what you are doing.

    Senior Business Analyst Interview

    Anonymous Employee in San Francisco, CA
    Accepted Offer
    Positive Experience
    Average Interview


    I applied through a recruiter. The process took 3 weeks. I interviewed at Twilio (San Francisco, CA) in May 2019.


    Recruiter reached out to me via LinkedIn about the role and we scheduled a phone screen. She did a great job aligning me with the expectations for the role, and was very accommodating to the questions that I had about specific requirements for the role. I felt as though I was being considered because I had specific skills and experiences as opposed to just another applicant in a pool of recruiter outreach. My recruiter was also very helpful in preparing me for what to expect from each step along the way, and never missed a deadline for followup.
    The first interview was with the hiring manager, which went very well to help me know what to expect from the team and management structure. This was very important to me in the hiring process so it was good to hear this upfront. This was followed by a phone screen the next week.
    Next was an onsite, where I was given a situation and asked to prepare a solution using the platform. The project was pretty open ended, which made it more challenging, but was a good opportunity to share my knowledge/understanding on the subject. This was followed by a 1:1 with the team's director, and a final check in with the recruiter. Again, she provided clear next steps and I left feeling confident of what to expect.
    The final step was a phone screen with a member of another team. My recruiter ensured I was prepared for this conversation, and we aligned on expectations for timing after this final screen. Throughout she was accommodating of my travel schedule as well, and I felt enabled during scheduling.
    When an offer was extended, I requested until the end of the week to finish my other interviews and weigh my options. Twilio was accommodating to this, and members of the team even offered themselves to provide any clarifying answers to questions I may have. My offer acceptance came after we negotiated a different start date, which Twilio was again accommodating to.
