e-Core Software Engineer Interview Questions
& Process

The process had three interviews. First was with a Headhunter, just to get general info about me, my XP, etc. It was really trivial. Part of this chat was in english to check my english skills. Second was with the team manager, he explained the position and the everyday job better, and deepened on my technical and previous jobs experience (some questions also in english). He also gave me a really simple technical test (how to remove duplicates from a list) to solve on my machine while sharing my screen. Third and last phase was a live coding technical interview, fully in english with the team tech lead. He asked me things related to the challenge and general questions about the job. The challenge wasn't hard, solved easily using Java core features. He asked some questions on why I used this or that, what I would do to solve a different problem, how I would add some new feature or deal with a corner case. All three phases were pretty smooth, the three interviewers were very gentle, understanding and willing.

The first interview was with the Recruiter and it was quite interesting, a good exchange, she asked relevant questions even in the English conversation. She mentioned that the company embraces diversity, that they respect differences, etc. There was a coding challenge and then an interview with the company professional + recently hired intern, which was also calm and interesting. The last stage was a video call with the finalists, the employees seem very happy and satisfied with what they do and this truly enchants those who wish to be called. Something that caught my attention was precisely the discourse of promoting diversity in the company, however, unfortunately, it seemed to me that in practice it might be different. On the panel there were men and women, all white, from the south (or southeast), it was mentioned in this interview that there are PCD collaborators on staff but... it struck me as strange not to see the discourse happen in practice.

First up was an HR interview, lasting about 20-30 minutes. Then, I had a technical interview with the local team lead for about an hour. After that, there was a take-home code challenge due in 3-4 days. Next, I had a technical interview with the client I'd be working with, around 30 minutes. Then came an architectural interview where I had to present a high-level design for an app, about 40 minutes. The challenge for this was emailed about a week prior, it's a tough one, so be ready. Following that, there was a cross-functional interview with a senior software engineer and a product owner. Finally, a management interview. The whole process was very polite and transparent, especially from e-Core HR.
