Coding Technical Presentation
It started with an online Python quiz, then a long home assignment on image processing. After that, the face-to-face part, which was pretty awful. We were in a room with 50 other students, listening to a 'propaganda speech' about the company. Then they split us into groups, and we just waited. The whole day felt wasted, and they only picked 2 out of 200 people. It felt like they were exploiting the current junior market. The actual interviews were easy enough: a basic LeetCode question, then a review of the home assignment. I didn't get an offer. Honestly, I did badly on the LeetCode question after sitting there for an hour, stressed out.
Confirmed questions1 question
- Tell me about your exercise and your understanding of kernels and convolutions, pretty basic image processing concepts.

Coding Technical Presentation
It was a six-stage interview. The first three stages were automated with video questions and online tests, no human interaction. Then, a quick 30-minute chat with two nice senior PMs. After that, a home assignment where I had to write a product sense style PRD for a random app, following very specific instructions. I didn't get the job because I didn't include a competitive analysis, even though the instructions didn't really provide a space for it and the other questions were super focused.

Technical Coding Behavioral Presentation
Started with a recruiter call for a quick intro. Then had a technical Zoom interview with two people where I was asked one technical question with sub-questions, focusing on coding without strict syntax checks. After that, I got a take-home assignment due in a week. This was followed by an in-person interview at their office to go over the assignment. This part included introducing myself, talking about my past experience and projects, and then diving into the assignment with some related technical questions. Later, I met with the team manager for an interview about the role, which also included a technical question and coding, again without a syntax focus. They're super fast with feedback, usually responding within a day or two after each step. The whole thing took about five weeks.
Confirmed questions1 question
- Can you implement an algorithm to find the nth Fibonacci number, given n, without using recursion?

Behavioral Technical Presentation
It started with an HR intro call, then I met with the hiring manager and another senior employee. After that, there was a home assignment. The next step was an on-site follow-up interview with the Hiring manager and another Senior team member, followed by two HR assessments. The HR team was great, super kind and communicative. However, during the intro call, they suggested a salary range much lower than the market rate. After every task I completed, I was told I did very well and that my home assignment and general knowledge were impressive. I made it to the 4th on-site interview, where recruiters and the hiring manager told me my knowledge was highly noticeable, and it seemed like they were just waiting to prepare the agreement. After over 30 days, I got a call a week later saying I wasn't the right fit due to a knowledge gap. I was shocked, especially after receiving such positive feedback throughout the 35-day process. It felt disrespectful of my time and effort.
