This was my initial interview for the Wix Boost program. It took place in a classroom setting on campus with about 60 other individuals. The interview itself consisted of five LeetCode challenges. Overall, it was a positive experience, and the staff members were very approachable. My main critique is that the interview solely focused on LeetCode problems, which I feel doesn't fully capture a candidate's potential.

Technical Coding System Design Behavioral
I had a call with a recruiter first. Then there was a 1.5 hour technical interview where they asked basic javascript questions and one algorithm question about finding the lowest common ancestor of two nodes in a binary tree. After that, I had a 3-hour technical interview where I had to implement my own version of the Mocha testing library. The final technical interview was 1.5 hours and focused on system design. They asked me to talk about a project I did and then design Google Sheets. I have to say, for the design interview, the two interviewers seemed like they had better things to do. They barely gave any details about the system requirements, rushed me when I was explaining my design choices, and asked very few questions about my solution. It felt like they weren't really trying to see if I'd be a good fit. A few days later, someone new called me (not the original HR) and said I didn't make it, with absolutely no feedback. This makes me think maybe this company posts jobs and interviews people without really intending to hire anyone, just to show investors they're growing. The position is still open, so other candidates probably got the same treatment.

Coding Technical Behavioral
So I had a simple pre screen exam, then a 4 hour react test in large groups. After passing that, they asked me to fix something in the test. Then came 2 typical technical interviews with normal leetcode style questions, and also an HR call.

- Can you fix the errors found in the 4-hour React test you completed?

Read reports →“Find the minimum cost to delete characters to ensure no adjacent characters are the same.”
Read report →“Given a 2D array with 1s and 2s, where every minute adjacent 1s transform into 2s, calculate the number of separate groups of 2s after this transformation.”
Read report →“Given references to two nodes in a binary tree, find the root of the smallest subtree containing both nodes in O(h) time and O(1) space. Note that one node might be an ancestor of the other.”
Read report →“Design an algorithm to move a turtle on a matrix given its starting position and a list of movements, then return its final location.”
Read report →“Given a matrix representing a map with land (0) and sea (1), how would you calculate the total number of distinct land areas? A landmass can be formed by connected '0's horizontally or vertically, and can span across multiple rows in shapes like 'H' or 'L'.”
