## Interview experiences

- **[Goldman Sachs · a year ago](https://www.aced.io/experiences/goldman-sachs-software-engineer-interview-1f574f)** — Software Engineer · Mid Level / L4
  > “5 rounds in total - Recruiter call, Initial Phone Screen, Superday with 2 Technical Rounds with 2 separate teams, 90mins each, Final Round with Hiring Manager”

- **[Barclays · 2 years ago](https://www.aced.io/experiences/barclays-software-engineer-interview-31230a)** — Software Engineer · Entry Level / L3
  > “The process was pretty smooth and well organized. The recruiter gave a clear idea of what to expect, and the interviewers were friendly and easy to communicate with. The technical rounds were challenging but reasonable (LC mediums + system design). Behaviorals were much smoother than the technical rounds. Just focus on company values for behaviorals. One thing that caught me off guard was how quickly some of the questions escalated in difficulty, so time management was probably the hardest part.”

- **[Oracle · 3 years ago](https://www.aced.io/experiences/oracle-software-engineer-interview-d8cb20)** — Software Engineer · Entry Level / L3
  > “Everything went well. What didn't go well was that I had a location preference, and the interview did not like it.”
