Had a ton of phone call interviews recently. Finally landed a new job but it took probably a dozen phone calls and 10 virtual interviews. I did well on the phone and procured the next step numerous times but didn't do well virtually.
Funny thing is, I only had two in-person interviews and both offered me the job.
Be prepared to talk about your resume and how the experience relates to the job you're applying for.
Know the job description well, or at least the best you can. This ties in to #1. On a 2nd step virtual interview, I stated I felt my current skills would line up well based on the job description. The guy then asked me how and I gave a shitty answer.
Prepare for popular interview questions, like why are leaving your current job, how have you solved disputes or worked with a difficult coworker, how you balance numerous deadlines, name a time you faced a difficult situation and how you overcame it, how you've added value to your current firm, what kind of work culture are you seeking or mesh well with, etc.
If you get the STAR format, good luck with that. Interviewed with Caterpillar and they used that. I prepped for it but the questions weren't straightforward and tripped me up.
Don't say anything negative about your current boss. Made it to the 3rd round with EQR and I could tell the old hag wanted to trip me up to narrow down the candidates with difficult / direct questions and tripped me up about my boss. It's almost like she knew my boss was a mega-bitch and wanted to hear me say it. Once the floodgates opened and I realized I messed up, I went scorched earth on prior mgmt lol. Not too bright, but learned something in the process.
Good luck!
