I applied through college or university. I interviewed at ADP in Feb 2023
Interview
Talked to them at a career fair and got a phone call to schedule an interview the next day. Interview was over video chat, with one 30 minute technical interview and 30 minute behavioral interview. The behavioral interview went well but during the technical interview the interviewer was clearly not paying attention to what I was saying and had already made a choice on me before the start of the interview. Waste of my time.
Interview questions [1]
Question 1
Talk about a time you were frustrated with a team member.
The process was well-structured and moved quickly through 3 distinct stages. Around 50 students were initially shortlisted.
Round 1 (Technical): Very project-focused. Since my resume was project-heavy, the interviewer dug deep into my previous work, architecture choices, and implementation. At the very end, the focus shifted to core DSA, specifically searching and sorting algorithms. 15 students cleared this round.
Round 2 (Managerial / Senior Managerial): This round was much more rigorous regarding specific ecosystem depth. The Senior Manager expected deep, granular knowledge of a specific language/framework ecosystem (in my case, Java and its various frameworks). I struggled a bit here as the questions required highly specialized framework knowledge rather than just general concepts. Only 6 students moved past this stage, and ultimately 4 received the final offer.
Round 3 (HR): Final standard behavioral check.
Advice to Management / Interviewers
The interviewers and the Senior Manager were incredibly friendly, professional, and welcoming. Even when I fumbled on the advanced framework questions, the feedback was constructive and helpful. Keep up the transparent and supportive candidate experience!
Interview questions [1]
Question 1
What sorting and searching algorithms do you know, and can you explain how they work under the hood along with their time complexities. And also write a code to implement Bubble sort and then binary search on it .
The whole process was straightforward and a little slow, but everything else was good. It was a great experience to attend this entire process, and the interviewers were friendly and supportive.
Online assessment followed by technical and hr rounds.
Online test was on testing platform for coding skills, and other rounds were in person on college campus for the shortlisted candidates.
