Twilio Software Engineer interview questions

got contacted by a recruiter after applying online, scheduled a phone interview a months later. First round phone interview was with a recruiter to chat for about 30 mins and followed by a Engineer Manager for about 45 mins. Talked about my experience and background, and then went on to solve two coding problems. Both was extremely easy: 1) fizzbuzz 2) reverse a string followed up almost immediately for a onsite interview. got lots of help from the HR on booking the flights and hotel for I was a non-local candidate. before the date of the onsite interview, I got a description of a small project which I should implement next day. the project was about simulating a online cloud infrastructure. This was pretty unexpected. Although I had some time to prepare and research for it. I couldn't complete it during the interview in the given time which was only 1 hr and half. And this was the only technical part of the onsite interview. And after a week I got a phone call with no offer. I was surprised on how easy you can get a onsite interview, yet how difficult and unconventional the onsite interview could become. I felt like if the company is looking a person with hands-on experience, they could maybe do another round of phone interview before sending candidates to onsite.

I applied online. Firstly, get a phone call from technical HR. Then follow a technical phone interview from a software engineer. After that I was invited to SF for an oniste interview, but this process was terrible. The recruiter almost never replied my email. And they helped me to book the flight just the night before the supposed flight day after 8 emails to the recruiter. There are 4 rounds onsite interview and no hard questions. After the oniste interview, the recruiter told me that I will get the feedback within 2~3 days, but actually I got the feedback after two weeks after 6 emails to her. Then she told me the feedbacks are positive and invited me an taking-home exercise and this process took another 3 weeks.....I just feel this company do not value the employees..So I declined this final exercise. I couldn't image what kind of life would be if I work for them.
