Anonymous Interview Candidate
I applied through other source. The process took 6 months. I interviewed at Two Sigma
I went through 13 interviews including a 5 hour project, on site meeting and was asked for a letter of recommendation. I was given zero transparency about the intricacies of the role but was pressed to give as much information as possible. Even after they asked for a letter of recommendation from a previous employer I was not extended an offer.
- Similar structure every time. Covering CV, hearing about interview's experience and then being asked from a list of questions.

It is well organized and the questions are similar to most tech companies. The morning interviews are technical. if you pass the morning sessions. There are behavioral interview sessions in the afternoon.
- Coding algorithm and resume behavior interview

two hour screening, 3 technical interviews (1 standalone + 2 back to back), didn't move onto behavioral interviews after the last 2 technical interviews. was honestly surprised i got the second two technical interviews, i got nowhere near finishing the question in the first one.
- the technical interviews were mostly medium-level leetcode i would say

First there's an online assessment, then a technical interview, then a two part final interview that is technical and behavorial. Although, it is possible to get cut after the final round technical interview and not make it to the behavorial. It was my first interview ever and I basically flunked every technical question (got 2/3 in the OA, first tech interview went awful as I had no clue what I was doing, final round was even worse). Although, somehow made it to the final.
- Why do you want to work there.

The second round was not easy. The process was quick and smooth. I chose Python, and the question was not easy to solve. I would recommend refreshing your Data types and algorithms knowledge.
- A usual coding challenge .

The interview process was short & ended after two rounds of 50 minute calls with PMs. These were generic & not matched to the specific team yet. Would consider interviewing again
- Tell me about your experience in x role on resume

Casual interview, great people that answered questions well The process itself was unorganized and not communicated clearly. I had two interviews lined up and then after my first one, the second one was cancelled. Also had to complete an assessment that I wasn't aware of beforehand.
- How do you stay organized?

The recruiter introduces themselves and the company, explaining the purpose of the call. you briefly introduce yourself, highlighting relevant experience and skills. The recruiter provides information about the company, culture, and specific job.
- What is your Background, Experience related to this position? Why Two Sigma?

OA, phone screen, then final rounds (technical + behavioral over two days). Process was a bit bumpy and stressful, but some of the interviewers were extremely kind and passionate people.
- Final: Graph traversal and graph backtracking optimization

1. Initial Phone Screen 2. 45 min chat with 1 product manager. Asking general background questions about career, why twosigma, etc. As well as an overview of the P&E org 3. Final round consisting of 5 1 hour long interviews, 1 engineering leader, 2 product mangers, 1 client side / experience manager and 1 quant engineer. This seemed extremely disorganized as all 5 interviewee's asked variations of the exact same questions as the previous interviewer (including from the prior round). I felt like I was giving repetitive answers for all five interviews. Everyone was polite and respectful and most interviewers did seem engaged. All in all, spending nearly 6 hours evaluating a candidate especially when there doesn't seem to be a goal with any particular interview (each person is just giving feedback on the same question/answer) seems like a huge waste of time for both parties.
- Tell me about yourself and your background.

What metrics did you use to measure success?
- How do you prioritize initiatives
- Why do you want to work here?
- What is your favorite product..if you were a pm for that product, how would you improve it
- Imagine that you worked here, what's something we should build?
