Kla-Tencor software engineer candidates describe a process that leans on data structures and algorithms, but its shape changes by team and level. The reports we have are mostly rejections, so treat this as a picture of what trips people up rather than a recipe for an offer.
Most accounts start with an HR screen. One candidate says HR asked for past payslips before the first interview, which surprised them. On the coding side, one software engineer describes a first round of three problems in an hour: tree lowest common ancestor, graph connected components, and a matrix dynamic programming problem. That was followed by a pseudocode round with DFS reachability, merging linked lists, and an LFU cache. A senior candidate describes a session of three difficult problems in one hour, where reading the questions alone took about twenty minutes. The same candidate also hit a sliding window problem and a math-style grid movement question.
Technical discussions go beyond puzzles. Candidates mention C++ and Java comparisons, multithreading, REST, mutable versus immutable behavior, and walking through a code review out loud. One software engineer was asked computer vision basics such as convolution and filtering. Another was asked to design Twitter, including classes and UML. Hiring managers often spend time on resume projects, so be ready to defend every technology you list.
Logistics are uneven: unclear round formats, canceled meetings, and slow movement between rounds. One senior candidate's process stretched over about two months. Practice timed problem sets in a plain text editor, and rehearse reviewing code you did not write, since both came up in reports.

Synthesized from candidate reports. Individual experiences may vary.
Candidates describe an HR phone screen ahead of the technical rounds, usually covering background and skills. One senior candidate reports a roughly 30-minute resume-based screen. Another had two HR conversations before the CV went to the hiring manager. One candidate says HR asked for past payslips before interviewing, so it is worth asking early what the process involves.
One report includes three problems in an hour (tree LCA, graph connected components, matrix DP), followed by a pseudocode round with DFS reachability, linked list merging, and an LFU cache. A senior candidate faced three difficult problems in an hour, including a sliding window problem, and spent about twenty minutes just reading them. That candidate was told to work in Word or Notepad. Formats seem to differ by team.
Candidates describe questions on C++ versus Java, multithreading, REST, mutable versus immutable objects, shallow versus deep copy, and explaining how a UI action flows through an application. One was asked to review code aloud, and one faced computer vision basics. Interviewers also dug into the technologies and projects on the resume, so expect to explain your reasoning, not just produce answers.
Design questions are less consistent across reports. One software engineer was asked to design Twitter, covering classes, UML, and requirements. A senior candidate was asked what diagrams they use to document software and how they would implement a public structure. Not every candidate describes a design round, so prepare to explain structure and trade-offs rather than count on one.
Later conversations involve the hiring manager and sometimes a director or HR. One software engineer had a 30-minute hiring manager round focused on relevant project experience plus a Python coding problem. Another reports a manager who drilled into designs from a current employer and left no time for questions. A senior candidate describes a managerial round followed by an HR discussion.
