National Instruments interview questions

Written Exam: The exam comprised two sections: 1. Aptitude Section: This section consisted of 15 questions testing general aptitude skills. 2. Core Electronics Section: This section also includes 15 questions focused on topics such as capacitors, Kirchhoff's Voltage Law (KVL), Kirchhoff's Current Law (KCL), and other core electronics concepts. Additionally, there were two coding questions: - Question 1: A problem related to a modified Kadane’s algorithm. - Question 2:A dynamic programming problem involving a knight’s movement on a chessboard. Technical Interview: The technical interview began with the interviewers introducing themselves, followed by my self-introduction. The interview then proceeded with a detailed discussion about my projects. Afterward, they asked me several coding questions, including: 1. Creating a "mountain array" from a given array. 2. The "Two Sum" problem. 3. The "Closest Two Sum" problem. 4. Problems related to rotational strings, and more. These questions mainly involved arrays and strings, ranging from easy to medium difficulty. Subsequently, the discussion shifted to electronics topics, covering areas such as digital electronics, digital communication, and sampling theory. HR Round: The final round was the HR interview, which focused on behavioral and situational questions. They asked about: 1. Why should we hire you? 2. What motivates you the most? 3. Have you ever guided or mentored someone? 4. How have you handled project challenges or team conflicts?

Incredibly unprofessional. After 3 rounds of HR nonsense interviews, two technical interviews, and one test assignment, which in total took up to 7+ hours, they couldn't even be bothered to send a rejection letter, or any sort of feedback. Even though, multiple times throughout the process I was told that I would not be left hanging, expect a response in 3 days, etc. I tried reaching out to multiple people, none replied, except for one HR person who just said that the recruiter is out of office. No return date or anything like that, and now it has been well over a month. Incredibly rude to have people go through your entire interview process then just ghost them. Especially when you are strongly implying during the interview that they will send an offer. They also kept setting up interviews while not really considering the 7 hour time zone difference. The company itself also didn't list out pay, benefits, and when asked, they pointed me to their career portal, which, again, had none of these listed out. I don't know if the blame is with the Hungarian office, or the US one.
