London Computer Systems Software Engineer Interview Questions
& Process

I had a behavioral phone screen that went super well. The person I talked to was super nice and friendly, and even gave me excellent feedback when I emailed her after the interview. However, the second "technical" phone screen was weird, my interviewer for this time seemed not very interested and less friendly, and even though I answered the majority of the questions correct (I did stumble on a few), I got rejected the next day.

I applied and about a week later I had a ~30 minute phone call with the technical recruiter. It was nice talking to her. I talked a bit about myself and my experiences. She asked me why I chose LCS, what I knew about LCS, and then told me a bit about the company and what they do. After that, I got set up for a 1h interview with a senior developer, which also went well. He asked me to tell him about myself, so I explained my career path, some of my projects, college, and internship experiences, and my programming language experience. There wasn't any live coding or whiteboard stuff, but he did ask a few algorithms questions to see how I thought about and discussed problems. We also talked about the same things I discussed with the technical recruiter, like 'What do you know about LCS?' and 'Why LCS?', and he talked about what LCS does and their products. Everything seemed to go really well, but then over the weekend I got an automated rejection email from their HR team late on a Sunday night. I suspected maybe the job posting had expired and a generic rejection email was sent, but that wasn't the case because I emailed the technical recruiter the next day asking for feedback on my interview, like what they liked and didn't like about my candidacy, thanking them for their time. I haven't heard back since, so I just left it at that. It was pretty strange and I felt a bit disrespected because of the abrupt, cold ending. Both the technical recruiter and senior developer seemed to like me, so I don't know why the ghosting happened. This could have been a 'Positive' experience instead of 'Neutral' if not for the weird ending.

So, there were 3 rounds in total. The first one was a phone call where they asked me about my past work. Then, the second round was a coding challenge, where I had to solve problems involving data structures and algorithms, and also answer some questions about databases.
