I applied for practice purposes before FAANG interview. If you want to work here, you can memorize the answer. all questions exist in glassdoor. Interviewers seem friendly but all process is not professional nor structural. -Code Signal 4 question but solving the first 2 questions is enough to pass it. You can take practice taking everyday before your online assessment. They are not exactly same but it gives an idea. The First 2 questions are really easy. 3. and 4th can be challenging. but they don't expect you to solve it. PowerDay 1. Design Round: the typical question exist here. It was a weird interview. One of the interview was sitting in a reclining position. He was too lazy to answer the questions. Sometimes I couldn't here what he said. 2. Coding Round: LeetCode easy One of the interviewers has a strong Indian accent. He only reads the question. I asked questions to clarify it but he didn't direct me correctly. I understood the real question in the middle of the interview. If they copied pasted the question on the Codesignal, it would be much easier to understand for me. 3. Behaviroul No issues here. He is also Indian but he was so much helpful. He repeated questions 2 times. Explained the star structure etc. Questions are typical behaviour questions. Conflict with team member. Time you had changing requirements to project and how did you handle it? 4. Case Round. The totally unnecessary part. The time was the end of the day. She was in the mood of complete the interview and go. She was also taking care of kid. I don't mind. it is ok we are all work from home but when I asked the question, I guess she missed or didn't understand correctly. She was destructed, tired and trying to speed up . Copied pasted lots of code blocks. She asked questions what is the output kind of questions. It is not difficult but the interviewer structure making hard to follow and understand what does she want. They can prepare more structured environment for those questions. Overall my observation is that this interview is great preparation for faang interviews. It is a free mock interview. Other than, I wouldn't want to work there. Salary is also average or under average.

4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
