  • “Adding stronger account security such as 2FA to your app is one of the simplest ways to increase security, protect users from cyberattacks, and build trust in your product, all while maintaining a smooth user experience,” - Andrew Baker, Manager of Developer Education at Twilio, on how to use Twilio account security using Node.js and MongoDB.

    Getting started with Twilio account security using Node.js and MongoDB

    One of the first considerations for developers building mobile and web apps is how to handle account security, namely how they're going to protect and authenticate their users and their data. The days where a username and password was sufficient to protect accounts are long behind us, and we're reminded of this nearly every day in the form of large-scale breaches, high-profile account takeovers, or massive digital heists.

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


    Twilio is by far the best company I have worked for (and I have worked at a few tech companies). It has this amazing culture of balancing work with play, of being inclusive of people and being led by a CEO who truly cares about the people. The work is interesting and innovative, and people are excited about what we are doing here. It really is a great group of smart, innovative and caring people. It is not perfect, normal bumps and warts, but you get the sense that management is trying to improve and grow the company.


    Honestly can not think of any cons right now. Health benefits could be a little better, but I assume as we grow that will happen. The new office location makes meals a little more challenging but I understand why they want us to get into the neighborhood (lunch is provided 2-3 days a week).

    Advice to Management

    Keep staying true to the culture.

    Average Interview


    The interview process was very smooth. Recruiting was very responsive and seemed genuinely interested in figuring out what team would be the best fit and moving me through the process.

    I had a phone call with a recruiter to determine team fit and a day of onsite interviews, but this may have been an abbreviated process since I was under time pressure from other companies. The onsite consisted of an architectural question (design an API, describe the backend with some constraints), a pair programming style interview, and behavioral interviews.

    Everyone I interviewed with was very friendly and seemed like folks I would enjoy working with. All in all, I really enjoyed the interviews compared to some more aggressive interview experiences I had with other companies.
