I applied online and was emailed by HR about the interview rounds. There were two phone interviews.

First, I spoke with a recruiting person who asked questions like, "What do you know about Twilio?" and "What are your expectations?"

Second, I had a coding interview via CoderPad. I was asked about my projects and then to write code to print anagrams from a file. I wrote an optimized version of the code and was pretty happy with the interview.

After three days, I received an email of rejection. I could not believe it because things went really well during the interview.

Nothing difficult. Standard coding questions.
