Texas Instruments coding interview
questions, leaked.
4 problems reported across recent Texas Instruments interviews. Top patterns: array, string, dynamic programming. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Texas Instruments pulls from a tight problem set, and four questions is all they need to separate candidates. You're looking at one easy, two mediums, and one brutal hard problem that spans array, DP, binary search, and bit manipulation. If you blank on any of these during the assessment, StealthCoder runs invisibly and surfaces a working solution in seconds. The real edge isn't memorizing solutions; it's knowing which patterns to drill first and having a safety net when the hard one lands.

You have a week, maybe less. You can't out-grind the list above. StealthCoder runs invisibly during the actual Texas Instruments OA. The proctor cannot see it. Screen share cannot detect it. Built because the OA filter rejects engineers who'd pass the on-site. That's a broken filter. This is the workaround.

Array and string problems dominate the dataset, each appearing twice, so those are your foundation. Dynamic programming shows up twice as well, which means TI isn't testing basic syntax; they want to see if you can optimize. The hard problem, Partition Array Into Two Arrays to Minimize Sum Difference, is a monster that touches DP, bit manipulation, and binary search all at once. Most candidates won't have time to fully understand that pattern before interview day. Group Anagrams and Generate Parentheses are the medium-difficulty gatekeepers. If you can solve those cleanly, you'll pass the easy round. For the hard, StealthCoder is your hedge. Even if you haven't drilled bitmask DP in production, invisible real-time support means you won't tank.

Memorizing every problem above in a week is a fantasy. StealthCoder is the hedge: an AI overlay that's invisible during screen share. It reads the problem on screen and surfaces a working solution in under 2 seconds. Built because the OA filter rejects engineers who'd pass the on-site. That's a broken filter. This is the workaround. Works on HackerRank, CodeSignal, CoderPad, and Karat.
Texas Instruments interview FAQ
Should I focus on arrays or strings first for TI?+
Both appear twice in their dataset, so you need both. Start with array problems like Group Anagrams and Partition Array since they tend to unlock hash-table and sorting patterns. String problems like Generate Parentheses rely on backtracking, which is less forgiving if you haven't practiced.
How much should I study dynamic programming for this company?+
DP appears in half their problems, including the hard one. Spend meaningful time on it, especially bitmask DP and subset-sum variations. If you run out of prep time, that's where StealthCoder saves you during the live assessment.
Is Merge Two Sorted Lists enough for the easy problem?+
Yes. TI has one easy problem, and it's a classic linked-list merge. If you can nail that in under five minutes, you've got breathing room for the mediums. Don't overthink it.
What's the biggest gap in my prep for TI?+
The hard problem pulls six different topics at once. Most candidates haven't seen that combo before. You can't reasonably master it in a week. Understand the approach, but treat it as the spike that StealthCoder covers if it appears.
How many full problem walkthroughs should I do before the assessment?+
All four problems from the dataset at least twice. The mediums are where most candidates slip. Group Anagrams tests sorting and hash clarity; Generate Parentheses tests recursion and state. Master those two, and you're in the top half.
