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.

- Tell me about your exercise and your understanding of kernels and convolutions, pretty basic image processing concepts.

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.

- Can you implement an algorithm to find the nth Fibonacci number, given n, without using recursion?

The interview process at Lightricks wasn't very clear or fair. I first did a take-home task where I had to design a web crawler. After that, I had a technical interview with some senior engineers and researchers, which went well. Then, HR told me I had one more round with the lead, and they said it would be a background discussion. But when I did the interview, it turned out to be another technical round focused on the same take-home task. It felt strange to have more technical rounds added after I thought I had passed the main stages. It's discouraging when the process isn't clear, especially after putting in the effort.

- Can you design a web crawler and explain how you would save the output to a file?
