Perguntas de entrevista da empresa NODAL EXCHANGE

Ultimately I was ghosted and never officially heard back from this company. A recruiter reached out to me to chat on LinkedIn. I was interviewing with several companies and this is the only recruiter where the recruiter didn’t set up an official time to do a recruiter screen and instead just tried to call me randomly for the next 3 days or would tell me he would call me then didn’t. Eventually he said the hiring manager was interested and we set up a technical interview. He gave me a list of times to choose from and I said any of the times provided on a certain day worked for me and he proceeded to schedule my interview for a time he didn’t initially provide. The technical was very technical and difficult. I also felt like the interviewer was condescending at times. She asked me what the time complexity is of retrieving an item in a hashmap. I make an educated guess because I didn’t have this memorized. She then asks me what the time complexity is if the item doesn't exist. Throughout this line of questioning she sounds so skeptical and I feel like an idiot because I thought I was incorrect. She then segues to asking about my undergrad career and how she hopes they taught me about data structures in my computer science program. Afterwards I look up those time complexities and I found out I wasn’t wrong so I don’t know why she questioned my education and made it sound like I had no idea what I was talking about. In that technical interview, there was live coding that wasn't leetcode style. After the technical, I followed up after 1.5 weeks because I didn’t hear back and the recruiter said they wanted to meet me for another interview and sent me times they had available. After, sending back my availability he never got back to me.

Three round interviews, and the final round will have three interviewers coming one by one. Handwritten codes are required, and also prepare statistics questions. Interviewers are nice and are really supportive. Technical questions are more than behavioral questions.
