Two Software Engineer candidates describe a process that opens with a screener and a coding assessment, followed by more technical and behavioral interviews. Both ended without an offer. One reports a HackerRank problem of easy-to-medium difficulty covering linked lists and heaps. The other describes a live session with an absolute minimum difference problem and a linked list question. Linked lists come up in both accounts, so they are a sensible place to start preparing.
Both also mention a code refactoring round. One candidate was given a class storing name, title and ID and asked to optimize and restructure it. The other was handed an existing chunk of code to optimize. A third candidate, interviewing for a Senior Software Engineer role, describes a different format: a three-hour take-home refactoring messy React and Redux code, then a code review of the submission. That is adjacent context rather than part of the Software Engineer pattern. In any refactoring round, practice explaining why you change the structure, not only how.
The system design prompts differ. One candidate was asked to architect a two-player online game, while the other had to design a REST API against requirements the interviewers provided. Practice clarifying requirements and talking through trade-offs aloud rather than memorizing one answer.
One candidate reports five interviews in total and a process of about a month. Another had a rougher experience: the job title changed, interview links broke twice, and two rounds were scheduled the day before. That is one person's account, but it is still worth asking early about the role level, the number of rounds and the schedule.

Synthesized from candidate reports. Individual experiences may vary.
Candidates describe opening with a screener, and one calls it a recruiter screener. Another used the call to say they wanted a senior role only if relocating to Boston, then struggled to get a clear overview of the role later. This is a good moment to confirm title, level and what the technical stages will cover.
One candidate reports a HackerRank problem of easy-to-medium difficulty on basic linked list and heap concepts. Another reports a live coding session with an absolute minimum difference problem and a linked list question. Linked lists appear in both accounts, so they are worth prioritizing in your preparation.
Both Software Engineer candidates report a refactoring round. One was given a class storing name, title and ID to optimize and restructure. The other was handed an existing chunk of code to optimize. Practice narrating the reasons behind each change, with attention to readability and complexity.
The design prompts reported differ. One candidate was asked to architect a two-player online game, and the other to design a REST API against requirements the interviewers supplied. Practice clarifying requirements, outlining components and explaining trade-offs, since the exact prompt may not repeat.
One candidate describes two behavioral interviews as typical culture and team-fit conversations, and another also lists a behavioral round. Prepare concise stories about past projects and collaboration. One candidate had rounds scheduled the day before, so confirm timings with your recruiter as early as you can.
