I applied online and recruiter contacted me two days later saying that engineering team directly want to get in touch with you, and wanted to schedule 1 hour phone interview. I scheduled the interview.
Interviewer called and introduced himself in 1 sentence - "I have been working at Robinhood for last xyz years and my recent project was based on xyz". He then asked me what I have been doing recently, followed by a coding question. I was expecting him to describe the role, but then thought he would describe towards the end (which he didn't do). The question involved receiving some data by calling HTTP GET, parsing the data, and display the data. Good thing was that I was allowed to use Google.
Once I started, he muted his phone. No engagement. He unmuted his phone only when I asked some question. It was kind of that I am talking to myself. It was so frustrating that I thought of saying bye to him mid interview. But anyways, I continued, but I decided that I am not going to move forward even if they do. The problem required me to print some int and float data combined with some static string, so I decided to convert int and float values to string and concatenate those with static string. I then realized that I could simply use fmt.Printf(), and use %d, %f etc, or some other way. But then I thought let's continue converting them to string. I was hoping that he would initiate some conversation, but no, no engagement. May be, he was working on his stuff, and was only interested in the final output.
One thing I didn't know was converting a string representation of time into a unix timestamp. Last 15 minutes, I asked if he wanted me to continue (converting string timestamp to unix timestamp) as I wanted to ask follow up questions. He said may be I can continue for 5 more minutes. After 5 minutes, he asked if I still wanted to continue working on it? To which I said no, I would like to ask some questions. I asked him some questions and thats it. After two days, I got an automated rejection email.
It is surprising that unlike Robinhood app, their interview process is not great.
