Got ghosted after the first round. Recruiter sent me link to hackerrank test for initial screening. There were couple of questions which were of medium difficulty with time limit of around 60 minutes. After completing the tests successfully I never heard back from recruiter.

Question 1
Given two arrays of strings, one containing the prefixes (area code) and one with a long string of numbers (phone numbers), return the longest prefix corresponding to all phone numbers.
Input is a string of characters that represents a text message. You need to segment this message into chunks of messages each of length 160 characters and add suffix "(1/5)" (representing pagination) at the end of each segmented message (Length of "(1/5)" is included in 160 length limit).
Thank you for your interest in Twilio and we so appreciate you taking the time to participate in the HackerRank test. I am sorry to hear that you didn't hear back from us, that is definitely something that need to do better on. Thank you for giving us the feedback and we will look at our process to make it better.
Other Software Engineer interview reviews for Twilio
I was given a take-home coding exercise, which was quite a bit more hefty than most others I've had. Sent a link to the public repo a few days later. The following week, the recruiter asked me to send the link I already sent. When I followed up the next week, I found that the recruiter's email bounced - they were no longer with the company. So I then emailed a higher-up, who passed me along to another recruiter, who I then sent my exercise to yet again. A rejection followed soon after with no feedback.
Phone screen and onsite with a few leetcode and system design questions. The overall process was professional and the recruiters did a good job of keeping me up to date.
