      Senior Software Engineer Interview

      15 Jun 2023
      Anonymous interview candidate
      London, England
      No offer
      Neutral experience
      Difficult interview

      Application

      I interviewed at National Grid (London, England)

      Interview

      30 or so questions about the history of computer science focussed on the technology the role uses. There was an expectation to have a lot of outdated knowledge. I don't have a CS degree but it seemed like that was a requirement from the questions asked.

      Question 1

      Prior to OAuth, what were some commonly used techniques for web API authentication? What were their limitations and drawbacks?

      Senior Software Engineer Interview

      17 Apr 2023
      Anonymous interview candidate
      Boston, MA
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 2 weeks. I interviewed at National Grid (Boston, MA) in Mar 2023

      Interview

      Applied online. After a couple days later, I had a phone interview. On the next day, they set up the 30-minute technical interview. It was about going through your background and the interviewer asked me some technical questions regarding front-end and back-end. I was a bit suprised for the interviewer to ask me back-end questions that required some of in-depth knowledge especially this was supposed to be for front-end. What was surprising that was when it came to front-end questions, the interviewer couldn't ask my any of front-end questions because of Jira page that she had front-end questions wasn't loading so she told me that she couldn't ask me the front-end questions. I was very confused because I thought she could at least asked me some front-end questions off of her knowledge or experience. On the same day, I was invited to panel interview. Panel interview was a mixture of front-end coding and system design, and behavioral questions. First part of panel interview raised a lot of red flags. It was with two engineers and they kept talking to each other that wasn't so related to the interview process. One engineer who was leading the coding & system design interview was interruptive and assumptive. For example, when we were going through some of front-end code exercise, whenever I didn't write the code he wanted, he kept saying "oh you don't know how to write (ie. async, parse functions ,etc), and I told him I know how to write those, but I decided to write (promise, intended to parse the data later, etc). He wasn't focusing on the efficiency, reusability, or performance of the code, just expected me to write the code the way he writes. So I wasn't so happy about him intereacting in a condescending manner. He kept doing it even during the system design. I wanted to wirte the high-level of the system architecture and add more details about the optimazation and other stuff later. But he kept insisting on desigining the way he wanted. I provided all the details at the end, but I was very frustrated. Another red flag is that when he was talking about the projects he worked on, he said "I was trying to work on this project in React, but we had to move on because of political issue". I don't think any of candidates wants to hear about political issue happening within the team. Also he mentioned that business / project staffs are very conservative so devs need to work around their decisions which is not good thing to here in agile environment. Behavioral interview with the next interviewer went well. Polite and respectful. After the interview, I sent an email when I would hear back, but they never responded back and ghosted me instead. I guess I should be glad that I dodged the bullet after seeing all these red flags. I had few interviews with this company and they never get back to you when they no longer consider you for the position.
