First-hand accounts from people who interviewed at Clear Street.
Software Engineer
I really enjoyed my interview with the developers; they were super collaborative and gave me helpful hints when I was stuck. The machine coding round involved a grid-based problem, which I managed to solve, although it was a bit of a struggle since it was my first time doing one. Afterward, we discussed performance optimizations and the reasoning behind my approach. I got positive feedback, and honestly, this is how frontend interviews should be – build something real and then dive into the details of improving it! I wish I had prepared more, as the interviewers made it seem like a great company.

Accounts Payable
Got an unprofessional email from the recruiter, no greeting, and no asking for availability. I had to ask when they were free. They didn't reply until the next day. Then they sent the invite 5 hours after I confirmed. During the interview, the recruiter seemed disengaged and cold. The interview was super quick, not even 10 mins out of the scheduled 30. I couldn't even talk about my strengths, and my questions at the end weren't answered well. They said they'd get back to me Monday/Tuesday. I followed up Tuesday morning, but got totally ghosted. It turned out to be a courtesy interview, and they already had someone else in mind. Such a waste of time.

Senior Frontend Engineer
HR reached out and set up an interview. The first round was a machine coding interview with a very experienced engineer. They asked me a React.js question about fetching and displaying data. I asked clarifying questions about the requirements, but the interviewer was unhelpful, telling me to 'Read the docs carefully.' I completed the coding challenge and was then asked a couple of concept-based questions. The interviewer seemed disengaged, often muted with his camera off. When I asked about the company's tech stack and goals, the answers were vague, just mentioning 'latest tech stack' even after I rephrased the question. I found out the next day I wasn't moving forward. Despite completing everything correctly, the interviewer's attitude made me suspect this outcome. I won't interview with this company again. It's unclear what they look for in candidates, and other reviews suggest similar experiences. I feel my time was wasted.

Office Experience Coordinator
The interview process for this role was surprisingly poorly managed, highlighting that companies also need to be evaluated by candidates. During the initial phone call, the interviewer disclosed that two individuals previously held this position, which made sense given the office spanned two floors. Despite remote work due to COVID, the expectations for a single person managing this space seemed unrealistic. The interviewer then proceeded to make the job sound even more demanding. Beyond operations for two floors, the role included being the face of the company as a greeter and acting as an executive assistant to the two CEOs, which involved running errands like picking up their lunches. A particularly concerning and inappropriate task was cleaning employee dishes, raising questions about why this wasn't the responsibility of those using them. The interviewer also listed duties typically handled by a porter. It became clear the company sought extensive work without fair compensation, essentially combining the responsibilities of an Office Manager, Executive Assistant, Receptionist/Admin Assistant, and a cleaning crew, far exceeding 'general office upkeep.' Despite the negative aspects, I asked about salary since 'Competitive Salary' was advertised. The interviewer claimed the salary was undetermined pending candidate discussions and experience evaluation, a common tactic to avoid disclosing a range and potentially lowball candidates. When pressed for a range, she stated that even a range was undetermined, which seems dishonest, especially for a high-volume brokerage firm. This lack of transparency is a major red flag, suggesting potential mistreatment if hired. It feels like an attempt to exploit desperation during the pandemic. While I doubt the interviewer is personally at fault, I expressed my disinterest based on these concerns. She offered to relay my feedback to superiors. Subsequently, I noticed the same job listing with a shortened responsibility list and the 'We offer' section, which previously mentioned competitive compensation, benefits, and perks, had been removed. Transparency is key to respecting everyone's time and avoiding unnecessary steps like phone calls or on-sites.
