I applied online. I interviewed at Flexport (Shanghai, Shanghai) in Jan 2025
Interview
The interviewer offered a question that conflicted with its example tests. Its example is required to finish a 2-sum problem transformed in hex format, but the question says to return a vector of indices. The interviewer seemed confident in his oral English, but his explanation of the questions was too brief to make the interviewee misunderstand.
Interview questions [1]
Question 1
Given an array of positive integers and a target integer, return an array of indices that two numbers sum up to the target number.
Example:
arr = ["0xF", "0x3", "0xA", ...], target = "0x0"
I applied online. The process took 4 weeks. I interviewed at Flexport (San Francisco, CA) in Mar 2026
Interview
Round-0: Recruiter call or Screening call
Recruiter was friendly and clearly explained about the company, role and team. Asked to tell me about myself, then a recent project experience
Round-1: Technical coding 1 (1hr)
Graph based question asked as two parts. Not a direct question leetcode question, but had to take an example myself and write the class and methods.
Round-2: Behavioral Interview with Engineering manager (1hr)
Introduced each other, talked about team and responsibilities of the role. Then she asked about my experience like challenging project, conflict, things that I learned from current experience those I haven't before. Some follow-up question about the project experience and so on.
This interview went well. I stumbled for few questions but overall its a good experience. Engineering Manager was so cool that she was talking and having a conversation rather than firing questions back-to-back.
Round-3: Technical coding 2 (1hr)
More real world based question. Has three parts. First two parts are to design the required classes and methods involving shipping yard, containers, buyers and sellers. The third part is to implement an algorithm to match the bidding between buyer and seller and conduct the transaction.
Two rounds of leetcode questions. Asked about your experiences first and then do one of two lc questions. Easy or easy medium level. Interviewers are very friendly and not stressful interview at all.
1. self introduction
2. a leetcode style problem, need to finish coding and test cases design, the code need to be complied and run successfully
3. any questions to ask interviewer
