Challenges in technical hiring
Long interview hours:
The team often spent hours interviewing candidates because they didn’t have a process to filter candidates effectively. There were times when a hiring manager would conduct at least 2 to 3 rounds of interviews per day to kick start the evaluation process. However, this proved to be time-consuming and inefficient.
Poor quality of candidates:
“We’d eventually realize that we’d been evaluating candidates who were not skilled enough for the job role. And we needed a way to speed up the hiring process and improve the quality of hires.”
– Ashwini J, Senior HR Manager, Kaleyra
Remote screening:
The team at Kaleyra found it difficult to increase it’s outreach and find the best talent on campus. Additionally, it was challenging to widen the network of colleges they wanted to visit, owing to logistical constraints.
“Earlier, we would ask candidates from other locations to come down to Bangalore for an interview, which was not always scalable and conducive.”
– Ashwini J, Senior HR Manager, Kaleyra
On the other hand, the team at Kaleyra would also visit campuses to hire junior developers. While this was a huge investment of their time and resources, the returns were poor. The team needed a solution to fix this immediately.
How HackerEarth changed the game
The recruitment team at Kaleyra decided to replace its existing assessment solution with a more powerful alternative.
Enter HackerEarth
“There are a couple of reasons why we zeroed in on HackerEarth. We were specifically hiring developers who were proficient in Node, PHP, Java, Python, and more. And HackerEarth has a robust set of questions that allowed us to evaluate candidates on these specific skills.”
– Ashish Agarwal, CTO, Kaleyra
Another big reason for choosing HackerEarth was the availability of the live video interview feature. This helped the team solve the problem of remotely evaluating candidates.
“Thanks to HackerEarth’s video interview feature, we didn’t have to force candidates to make a trip to the office for a face-to-face interview anymore. We found that using video interviews, we were able to gauge a candidate’s skills precisely. More importantly, we were able to determine high quality candidates by evaluating their logic and assessing their coding skills in real-time.”
– Ashwini J, Senior HR Manager, Kaleyra
This made it easier for recruiters and hiring managers to take collaborative hiring decisions.
The HackerEarth advantage
- Assess candidates for different roles: Kaleyra uses HackerEarth to evaluate engineering graduates for entry level positions as well as experienced developers for senior positions. The team was able to hire even for niche roles, owing to the exhaustive list of questions in the HackerEarth library. With the help of HackerEarth, Kaleyra hired front end developers, devops engineers, full stack developers, quality analysts, and more.
- Improve quality of hires: Using HackerEarth, the team had a fool-proof mechanism to filter candidates before deciding to shortlist them for interviews.
“With the help of HackerEarth, now we’re able to screen and filter only high quality candidates and move them to the interview stage. This has significantly reduced the time, cost, and resources that we would otherwise have spent in hiring developers.”
– Ashish Agarwal, CTO, Kaleyra.
- Reduce the number of interviews: By interviewing only candidates who cleared an assessment, hiring managers were able to save significant engineering hours and cut down on the time taken for conducting interviews.

“The experience with HackerEarth has been great so far. The platform has helped us reduce the number of interviews to evaluate candidates by 50%. And that’s been a huge relief!”
– Ashwini J, Senior HR Manager, Kaleyra
- Save cost and resources: The video interview features came in handy for the team, especially when they had to hire developers from remote locations. This helped the team save a significant amount of time and money.
- Streamline recruitment workflow: By integrating HackerEarth with their ATS (FreshTeam), Kaleyra had complete visibility of its recruiting funnel.
