Qualtrics Software Engineer I interview questions

Had one HR phone interview, and one round phone interview. Then got four-round onsite interviews. People are friendly. Mainly technical. - Number of Islands - Serialize and Deserialize - Regular Expression - Counting Sort - Longest palindromic substring It is strange that there is no design related question asked. Basically it will be helpful to nail the online OJ. However, if you really nailed the OJ, you will probably already get an offer in other big names. (Facebook, Google, etc)

I had a phone interview a couple months after I applied. The developer interviewing me seemed to be busy doing something else during the interview. He asked about previous projects, motivations for software development, and basic computer science questions such as big O and comparisons of different data structures. After the phone interview I had an on-site interview where there were three in person interviews. They really pitched the start-up nature of the company. This seemed to include working long hours as one of the developers who interviewed me mentioned he works 8am-6pm with some late nights. The HR folks and developers ended up giving off a feel similar that of companies parodied on the show Silicon Valley, i.e. "we're changing the world with our cat pictures app", "disruptive technology", etc. While I didn't particularly care for their culture it was obvious they had very smart people working there.
